Answer:

T = 1300

Step-by-step explanation:

Given

Radius, r = 9\ in

Height, h = 14\ in

<em>See attachment</em>

<em></em>

Required

Determine the total surface area, T

T is calculated using:

T = 2\pi r(r + h)

Substitute values for r and h

T = 2\pi  * 9(9 + 14)

T = 2\pi  * 9(23)

Remove bracket

T = 2\pi  * 9*23

T = 2\pi  * 207

Take \pi = 3.14

So, we have:

T = 2 * 3.14 * 207

T = 1299.96

T = 1300 --- approximated.

<em>Hence, the surface area is 1300 square inch</em>
