Answer:
Volume of hemisphere =
[tex] \frac{2}{3} \pi \: r {}^{3} [/tex]
Given volume =
[tex]18\pi \: cube[/tex]
[tex] \frac{2}{3} \times \frac{22}{7} \: {r}^{3} = 18 \times \frac{22}{7} [/tex]
So pi is there on both the sides so it will be cut from both LHS and RHS
[tex] \frac{2}{3} \times r {}^{3} = 18[/tex]
[tex]2 \times r {}^{3 } = 18 \times 3[/tex]
[tex]2 \times r {}^{3} = 54[/tex]
[tex]r {}^{3} = \frac{54}{2} [/tex]
[tex]r {}^{3} = 27[/tex]
[tex]r = 3[/tex]
Therefore value of r=3 inches

A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?
Answers
Answer:
85 ft^2
Step-by-step explanation:
Ok, the square base area is 5 x 5 = 25 square feet
the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.
To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.
15 x 4 = 60 + 25 = 85 square feet

IF we say 3 triangles can be fit into a polygon given 2 sides then we 180 x 3 = 560 degree if its 3 rectangles then if it is easier to make 4 rectangles if square shape we can subtract the smaller measures of the missing rectangle.
With triangles;
The number of triangles is always 2 less than that that of its sides.
= 3 triangles + 2 = 5 sides.
The sum of interior angles
(n-2) x 180 = 540 degree
5-2 x 180
To determine the amount of sides; we remember
(n-2) 180
360 = (n-2) 180
+360 = 180 -360 +180
+360 = 180 = (3 triangles with 180)
900/180 = 5 sides.
If we say 5 triangles created with 3 given lengths
then same rule applies n-2 (180)
=7 sides

There are many cones with a height of 12 inches. Let r represent the radius and V
represent the volume of these cones.
Plot points that show the volume when r=1, r=2, r=3, and .r=4.
HELP!
Answers
Answer:
If R = 1, ~12.57 is the y. (r is the x.)
If R = 2, ~50.27
If r = 3, ~113.1
If r = 4, ~201.06
Step-by-step explanation:
The formula of a cone is pi * r^2 * h/3
If r = 1, we have pi * 1^2 * 12/3
12/3 = 4
and 1^2 = 1
pi * 1 * 4
4 * pi = ~12.57
if r = 2, we have an imrpoved formula,
pi*2^2 * 4 (h/3 became 4 since 12/3 = 4)
2^2 = 4
4*4 = 16
pi * 16 = ~50.27
If r = 3
our formula is pi*3^2*4
3^2 = 9
pi*9*4
9*4 = 36
36* pi = ~113.1
If r = 4,
our formula is
pi*4^2*4
4^2 = 16 and 16*4 = 64
pi*64 = ~201.06.
Answer:
If R = 1, ~12.57 is the y. (r is the x.)
If R = 2, ~50.27
If r = 3, ~113.1
If r = 4, ~201.06

V represents the vacation hours and H is the hours worked
If they both work 2080 hours
V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)

find surface area of the prism pls!!!!! explain too. I really need help!!!
Answers
Answer: 104 square inches
Step-by-step explanation:
The surface area of a prism is the sum of the surface are of all of it's faces.
We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.
Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)
Simplify with multiplication to get this: SA = 24 + 20 + 60
Simplify with addition to get this: SA = 104
Add the unit label and you get 104 square inches.
