Question

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

Answer 1

Answer:

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

Step-by-step 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

Answer:

$120\pi yd^2$

Step-by-step 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;

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

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