Find the volume of a right circular cone that has a height of 18.8 m and a base with a
radius of 19.3 m. Round your answer to the nearest tenth of a cubic meter.
Step-by-step explanation:
Height of the right circular cone = 18.8 metres
And base is 19.3 metres
Volume of the right circular cylinder is given by,
= πr²h
= 3.14 × (19.3)² × 18.8
= 21999.98(approx.) cubic metre
Rounding off nearest tenth
= 21999 cubic metres
The volume of the right circular cone is 280,199.5 m³
What is a right circular cone?
'A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.'
According to the given problem,
Height = 18.8 m
Radius = 19.3 m
Volume of right circular cone = [tex]\frac{\pi r^{2}h }{3}[/tex]
= [tex]\frac{\pi * 19.3^{2} * 18.8}{3}[/tex]
= 280199.499 m³
= 280199.5 m³
Hence, we can conclude that the volume of the right circular cone is 280199.5 m³.

Step-by-step explanation:
13. The function y=16 cos(x)+k has a minimum value of -4. What is its maximum value? Explain.
Answer:
It's maximum value is 28.
Step-by-step explanation:
Cosine function:
The cosine function has the following format:
[tex]f(x) = A\cos{x}[/tex]
The difference between the maximum and minimum point is 2A.
y=16 cos(x)+k
A = 16, so 2A = 32.
Minimum value of -4. What is its maximum value?
[tex]M - (-4) = 32[/tex]
[tex]M + 4 = 32[/tex]
[tex]M = 32 - 4 = 28[/tex]
It's maximum value is 28.

Answer:
b= (3z-6)/(1+3z)
Step-by-step explanation:
z=(-b+6)/(3b-3)
cross multiple
z(3b-3)=-b+6
open the bracket
3bz-3z=-b+6
make -b the subject of the formula
-b = 3bz-3z-6
-b - 3bz = -3z - 6
factorize the left hand side...
-b(1+3z) = -3z-6
make -b the subject of the formula again
-b = -(3z-6)/(1+3z)
cancel the minus at both sides...
b = (3z-6)/(1+3z)
Answer:
b = [tex]\frac{3z + 6}{3z+1}[/tex]
Step-by-step explanation:
Simply solve for "b" , so the formula will be
b = .....
z = [tex]\frac{-b+6}{3b-3}[/tex] ( b > 0 )
z(3b - 3) = - b + 6
3zb - 3z = - b + 6
3zb + b = 3z + 6
b( 3z + 1 ) = 3z + 6
b = [tex]\frac{3z + 6}{3z+1}[/tex]
Find the area of this triangle in square centimeters .
Step-by-step explanation:
The answer is 24 I think.
using the formula for finding the area of a triangle, which is....
Area= b times height divided by 1/2 or 2
First step is to multiply 6 which is the base by the height 8 to get 48. Then 48 divided by 2 is 24.
Step-by-step explanation:
the area of the triangle can be find by using the heron's formula...
that is:
√s-a×s-b×s-c
So,
a=8cm,b=6cm,c=10cm
Semi perimeter= 8+6+10/2=24/2=12
√12(12-8)(12-6)(12-10)
=√12×4×6×2
=√ 2×2×3×2×2×2×3×2
= √2×2×2×3
= 12 cm...

Answer:
384 ft, this is the required answer
Answer:
area of shaded part = 512 ft^2
Step-by-step explanation:
find area of rectangle
length = 32 +8
=40 ft
breadth = 8 + 8
=16 ft
area of rectangle = l*b
=40*16 ft
=640 ft
since there are two square .we should find the area of two sqaure.
length = 8 ft
area of square = l^2
=8^2
=64 ft^2
area of another square = l^2
=8^2
=64 ft^2
area of shaded part = area of rectangle - (area of square + area of square)
=640 -(64 + 64) ft^2
=640 - 128 ft^2
=512 ft^2

Joseph and Mark have $230. Joseph and Kevin have $130. Mark had 3 times as much money as Kelvin. How much money does Kelvin have?
Answer:
Step-by-step explanation:
Let's call Joseph "J", Mark "M", and Kevin "K" for ease. We need a system of equations to solve this, 3 equations for 3 unknowns. The first equation is
J + M = 230. The second equation is
J + K = 130. The third equation is
M = 3K. Sub that 3K into the first equation and get
J + 3K = 230. Now take th second equation and solve it for J:
J = 130 - K. Now sub 130 - K into the re-written first equation to get a whole new equation in terms of K only:
130 - K + 3K = 230 and
2K = 100 so
K = 50
Kevin has $50
Let $z$ and $w$ be complex numbers satisfying $|z| = 5, |w| = 2,$ and $z\overline{w} = 6+8i.$ Then enter in the numbers \[|z+w|^2, |zw|^2, |z-w|^2, \left| \dfrac{z}{w} \right|^2 \]below, in the order listed above. If any of these cannot be uniquely determined from the information given, enter in a question mark. Don't even know where to start.
I got 49 for the first one, 100 for the second one, 9 for the 3rd one, and 6.25 for the 4th one. But it was wrong, so I don't know how to do this question.
Answer:
1st entry: 41
3rd entry: 17
Step-by-step explanation:
The 1st and 3rd entry are incorrect.
We will use the following for the 1st and 3rd:
[tex]|z+w|=|z|^2+|w|^2+2R(z\overline{w})[/tex]
[tex]|z-w|=|z|^2+|w|^2-2R(z\overline{w})[/tex]

A shoe repairman is working with his assistant, who takes 1.5 times as long to repair a pair of shoes.
Together they can fix 10 pairs of shoes in six hours. How long does it take the repairman to fix one pair
of shoes by himself?
Answer:
1/2 or 0.5 hours
Step-by-step explanation:
r = time for repairman to fix one pair of shoes.
a = time for assistant to fix one pair of shoes.
a = r×1.5
x×r + y×a = 6
x = number of pairs of shoes repaired by repairman.
y = number of pairs of shoes repaired by assistant.
x+y = 10
y = 10-x
x = y×1.5 (based on the a/r ratio : as the assistant needs 1.5 times longer, the repairman will have repaired 1.5 times more pair of shoes in the same time)
y = 10 - y×1.5
y + y×1.5 = 10
2.5×y = 10
y = 4
=> x = 6
6×r + 4×r×1.5 = 6
6×r + 6×r = 6
12×r = 6
r = 6/12 = 1/2 or 0.5 hours
Which function is graphed below?
Answer:
[tex]g(x)=\sqrt{x+2}[/tex]
Step-by-step explanation:
Parent function of the given graph is,
f(x) = [tex]\sqrt{x}[/tex]
If the parent function is shifted 2 units to he left the new function or image function will be,
g(x) = [tex]\sqrt{x+2}[/tex]
Therefore, graph will represent the graph of the function g(x) = [tex]\sqrt{x+2}[/tex].

To find:
The value of x.
Solution:
We have,
[tex]\dfrac{1-x}{11}=6[/tex]
After multiplying both sides by 11, we get
[tex]1-x=66[/tex]
[tex]-x=66-1[/tex]
[tex]-x=65[/tex]
Multiply both sides by -1.
[tex]x=-65[/tex]
Therefore, the value of x is -65.
