Question

EASY MATH HELP!?!?!?!

Answer 1

The answer would be D) 7065 ft2

Answer 2

The radius of the cylindrical tank = 15ft.

Height of the cylindrical tank = 60ft.

We know that the surface area of cylinder = $2\pi r^2+2\pi rh$

Here, r = 15ft and h = 60ft.

By placing the values in the formula we will get,

Surface area = $2\pi (15)^2+2\pi (15)(60)$

= $2\pi (225)+2\pi (15)(60)$

= $450\pi +2\pi (15)(60)$

= $450\pi +2\pi (900)$

= $450\pi +1800\pi$

= $2250\pi$

= $2250(3.14)$, as given $\pi = 3.14$

= $7065$

We have got the required answer.

Surface area of the tank = $7065 ft^2$

The correct opttion is D.
