Question

What is the surface area of a right circular cylinder with a height of 8 meters and a base whose

radius is 4 meters?
(A)144 m2 (B)96 m2 (C)80 m2 (D)128 m2

Answer 1

`S.A=96\pi m^2`

Explanation:

The surface area of a right circular cylinder is given by the formula;

`S.A=2\pi r(r+h)`

where
`h=8m` is the height of the cylinder and

`r=4m` is the radius of the cylinder.

We plug in these values into the formula to obtain;

`S.A=2\pi *4(4+8)`

`S.A=8 *12 \pi`

`S.A=96\pi m^2`
