Answer:

T = 1300

Explanation:

Given

$Radius, r = 9\ in$

$Height, h = 14\ in$

See attachment

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.

Hence, the surface area is 1300 square inch
