Question

A tin is a right circular cylinder with a diameter of 4 meters and a height of 6 meters. What is the surface area of this tin, in terms of pi?

Answer 1

32

Explanation:

did it in edge

Answer 2

32 pi m^2

Explanation:

The surface area of a cylinder is given by

SA = 2pi r^2 + 2 pi rh

The diameter is 4 meters so the radius is 1/2 of the diameter = d/2 = 2 meters

SA = 2 * pi * (2)^2 + 2 pi *2*6

= 8pi +24pi

= 32 pi m^2
