Step-by-step explanation:
The height $h$ and the base area $B$ of a cone are given. Find the volume of the cone. Write your answer in terms of $\pi$ .
$h=6$ units
$B=4\pi$ square units
The volume is__ cubic units.
Answer:
(i) 84 cm.
(ii) 5635π cm^2
Step-by-step explanation:
(i)
The volume of the cone = 1/3 π r^2 h
= 1/3 π 35^2 h.
The volume of the hemisphere = 2/3 π 35^3.
As the volume of the cone is 1 1/5 ( = 6/5) times the volume of the hemisphere:
1/3 π 35^2 h = 2/3 π 35^3 * 6/5
h = 2/3 π 35^3 * 6/5 / 1/3 π 35^2
h = 84 cm (answer).
(ii) Surface area of the hemisphere = 2 π * 35^2 = 2450π cm^2.
Surface area of the cone = π r l where l = slant height.
l = √(35^2 + 84^2) = 91 cm.
So the surface area of the cone = 35*91 π = 3185π.
So the total surface area of the solid is 3185π + 2450π
= 5635π cm^2.
i hope this work for you
The height and the base area of the cone are 6 units and 4π square units. Then the volume of the cone is 24π.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The height (h = 6) and the base area (b = 4π) of a cone is given.
Then the volume of the cone will be
Volume = b × h
Volume = 4π × 6
Volume = 24π

Answer:
original coordinates A[-4,5], B[-3,1], C[-5,2
new coordinates [3,1], B[2,5] C[4,4]
Step-by-step explanation:
ok so the x is the horazontal line and the Y is the vertical line when your writing cooodinates you always write the X first then the Y. so to find the origanal corrdinates which i'm assuming are the coordinates for the blue triangle you have to find the first point so the one labled A, you look at the numbers on X so the horizontal line, and find out which number on that line has point A on it and you record that number this is the X then you look at the numbers on the Y line, (the vertical line) and see which number has point A on it and record this number this is the Y do this for all the other points and you will have all of their coordinates.

i need someone else to check this because i mooted it on a break.
Step-by-step explanation:
For a, we can solve for the larger rectangle and the smaller rectangle and subtract the smaller rectangle's area from the larger one. 12*5=60 and 3*8=24. 60-24=36.
For b, we can do the same thing, solving for the larger shape then the smaller. We can break up the shapes. We can split the larger shape into a rectangle measuring 17 by 36 and a rectangle measuring 14 by 11. This will give us a total area of 766. The smaller shape can be split into 7*7 and 6*18 with a total area of 157. The resulting number from the subtraction is 609.
for c, We can find the triangles. The picture shows that the 8cm side is broken in to parts of 4. the area of the larger is 24, and the smaller 6. the resulting number is 18.
for d, we can find the larger rectangle and the triangle. 12*4=48, and the triangle seems to be isoceles, so it's area is 18. The area of the shaded part is 30.

I WILL MARK BRAINLIEST! This is a multiple choice question!
Here is a system of linear equations:
6x-y=18
6x−y=18
4x+2y=26
4x+2y=26
Select all the steps that would help eliminate a variable and enable solving.
Group of answer choices
A. Multiply the first equation by 4 and the second equation by 6, then subtract the resulting equation.
B. Multiply the first equation by 2, then add the result to the second equation.
C. Multiply the first equation by 2, then subtract the second equation from the result.
D. Multiply the second equation by 6, then subtract the result from the first equation.
*I am assuming that each equation only appears once instead of twice in this problem
6x-y=18
4x+2y=26
We are solving by elimination, and to do that, we need to make the coefficient of one of the variables the same for both equations. The easiest way would be to multiply the top equation by 2 which would result in
12x-2y=36
4x+2y=26
As we see now, -2 and +2 can cancel out if we add the two equations together. So B is correct.
The other solution to this problem is to get a common coefficient for x to do that we first find the least common multiple of 6 and 4 which is 12
so to get 12 we need to multiply equation 1 by 2 and equation 2 by 3
resulting in 12x-2y=36 and 12x+6y=78 which we can solve by subtraction
Although this second way works, we have to realize that this is not one of the solutions. Instead the solution proposed to multiply by 4 and 6 which actually is just what I did above but multiplying everything by 2 again.
In conclusion, the answers should be A and B

landen's front yard lawn measures 20 feet by 8 feet. he counts to find that there are 120 blades of grass per 1 square inch. how many blades of grass are in the entire lawn?
Answer:2764800
Step-by-step explanation:First step is to convert feet into inches:
1 foot = 12 inches
20feet = 20*12=240 inches
8feet = 8*12=96 inches
Now we can calculate total area:
A = height * width
A= 240 * 96
A=23040 inches²
We know the amount per one inch² and we need to find out total number of blades:
1 inch² 120 blades
23040 inches² x blades
Now we cross-multiply numbers:
1*x = 23040 * 120
x= 2764800
There are total of 2764800 blades in the entire law

Choose the quadrants on a coordinate plane which represent the location of an (x;y) pair satisfying the following equation: |x|+|y|=|x+y|
Answer:
On any quadrant you choose the points each will always be positive
Step-by-step explanation:
The absolute value of a negative number is positive and the same goes for a positive number (the absolute value will always be positive) because it is how many numbers it is away from 0. For Example; the absolute value of -4 is +4 because it is 4 numbers away from 0. If |x|+|y| = |x+y| then an example would be |-4| + |3| = |-4+3| it would be 7 because the |-4| is 4 and the |3| is 3 giving you the sum of 7

2. How many ounces of sauce did you buy?
3. Num. Guest 0ω0
Worth 10 points . . .
Answer:
13 guests, 72 ounces of dough, 58 ounces of sauce

6 ounces of dough plus 4 ounces of sauce is 10 ounces so 130 divided by 10 is how you get your guests. Then multiply both 6 and 4 by 13 to get the ounces of both dough and sauce
The balance of an account after t years can be found using the expression 6000(1.02)^t where the initial balance was $6000. By what percent does the account increase annually? a 1.02% b 102% c 0.02% d 2%
9514 1404 393
Answer:
(d) 2%
Step-by-step explanation:
The base of the exponent is the "growth factor". It is 1 more than the "growth rate", the fraction of change in 1 year.
growth factor = 1 + growth rate
1.02 = 1 + 0.02
growth rate = 0.02 = 2%
The account increases 2% annually.
