Question

Use the net to find the surface area of the cylinder. Give answer in terms of pi.

Answer 1

The correct answer option is 120
`\pi yard^2`.

Explanation:

We are given a cylinder with a radius of 5 yard and a height of 7 yard and we are to find the surface area of this cylinder.

We know that the formula of the surface area of a cylinder is given by:

Surface area of cylinder =
`2\pi rh+2\pi r^2`

Substituting the given values in the formula to get:

Surface Area =
`2\pi *5*7+2\pi *5^2` = 120
`\pi yard^2`

Answer 2

`120\pi yd^2`

Explanation:

The surface area of the cylinder is given by;

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

The radius of the cylinder is
`r=5yd.` and the height is
`r=7yd`

Substitute the values to get;

`T.S.A=2\pi * 5(5+7)`

`T.S.A=120\pi yd^2`
