Question

The value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x.

The radius is 7.2 and the height is x, find x

Answer 1

Radius, r = 7.2
Height, h = x

Surface of the cylinder
2*pi*r*x

Volume of the cylinder
pi*r^2*x

2*pi*r*h = pi*r^2*h
2 = r
