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

Is Frieda’s work correct? Explain how she can check her solution.
z + 22 = 64
z + 22 – 22 = 64 – 22
z = 42
Answer:
Frieda should substitute 42 for z in the original equation, and simplify to see if it is a true statement. 42 + 22 = 64, so her solution is correct

find an equation of the line that has a y intercept of 5 and is perpendicular to the graph of the line 4x+3y=8.
Answer:
3x-x+2=4
Step-by-step explanation:
You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.
Answer:
y = 3/4x + 5
-3x + 4y = 20
Step-by-step explanation:
In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)
First change that standard form equation to slope-intercept form:
1. 4x + 3y = 8
2. 3y = -4x + 8
3. y = -4/3x + 8/3
Step 1 is given.
In step 2, 4x was subtracted from both sides.
In step 3, both sides were divided by 3.
Slope-intercept form:
y = mx + b
m is the slope and b is the y-intercept.
m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)
b = 5; the y-intercept was stated in the problem
Now, you put it together: y = 3/4x + 5
Standard form:
You can just change the slope intercept form back into standard form by moving the numbers around a bit:
1. y = 3/4x + 5
2. -3/4x + y = 5
3. -3x + 4y = 20
Step 1 is given.
In step 2, 3/4x was subtracted from both sides of the equation.
In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)

What is the distance between (-8, 5) and (6, 5)?
Enter your answer in the box.
___ Units
Answer:
distance: 14
explanation:
[tex]\sf \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
given:
(-8, 5) and (6, 5)solve:
[tex]\sf \rightarrow \sqrt{(5-5)^2+(6--8)^2}[/tex]
[tex]\sf \rightarrow \sqrt{(0)^2+(14)^2}[/tex]
[tex]\sf \rightarrow \sqrt{14^2}[/tex]
[tex]\sf \rightarrow 14[/tex]
Solution:
We know that:
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
Finding the coordinates
(x₁,y₁) = (-8,5) = x₁ = -8; y₁ = 5(x₂,y₂) = (6,5) = x₂ = 6; y₂ = 5Substitute the coordinates into the distance formula.
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6- (-8)]^{2} +[5-5]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6 + 8]^{2} +[0]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[14]^{2}[/tex]
[tex]\rightarrow \boxed{\text{Distance }=14 \ \text{units}}[/tex]

In this question as two straight lines intersect each other
we use vertically opposite angle axiom
so 74 degree = 2x.
then x= 74/2= 37degree
Answer:
Angle 74 degrees and 2x are vertical, so they would have to equal each other.
Note: Vertical angles are congruent meaning they measure the same degrees
So we set up the equation;
74 = 2x
/2 /2
37° = x
