Question

A cylinder has a radius of 2 cm and a height of 8 cm. The surface area of the cylinder is _____ cm².

Answer 1

Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h. (h is the height of the cylinder, r is the radius of the top).

Answer 2

The surface area of any cylinder with radius 'r' and height 'h' is


SA = 2*pi*r^2 + 2*pi*r*h


In your case, the radius is 2. So r = 2. Also, the height is 8, so h = 8.

Answer 3

2*3.14*4(2^2=4) * + 2*3.14*2*8
