36pi = 4/3 * pi * r^3
27 = r^3
r = 3 in

The equation for volume of a sphere is (4/3)πr^3, and you want to solve for r, so:
(4/3)πr^3 = 36π
÷ 4/3
πr^3 = 27π
÷ π
r^3 = 27
(cube root)
r = 3

So the radius is 3, I hope this helps!

The total surface area of a cube is 96cm2, find its volume.

Setler [38]

Answer:

$\huge\boxed{V=64cm^3}$

Step-by-step explanation:

The formula of a surface area of a cube:

$SA=6a^2$

The formula of a volume of a cube:

$V=a^3$

We have

$SA=96cm^2$

Calculate the edge length (<em>a</em>).

$6a^2=96$ <em>divide both sides by 6</em>

$a^2=16\to a=\sqrt{16}\\\\a=4(cm)$

Calculate the volume of a cube:

$V=4^3=64(cm^3)$
