Question

The volume of a cylinder of height 8 cm is 72π cm3 Find the radius of the cylinder.

Answer 1

Answer:

3 cm

Step-by-step explanation:

Divide the volume by the height

72π/8 = 9π

Now we have the surface area. The surface area is π$r^{2}$, so we reverse it.

Divide the number by π:

9π/π=9

Now we find the square root

3 x 3 is 9, so 3 is the square root and radius.
