Answer:

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:

$120\pi yd^2$

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;

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

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