Answer:

$Area = 339.29\ in^2$

Explanation:

Given

See attachment

Required

Determine the total surface area

From the attachment:

$r = 3\ in$ --- radius

$h = 15\ in$ --- height

The total surface area:

$Area = 2\pi r(r + h)$

Substitute values for r and h

$Area = 2\pi * 3(3 + 15)$

$Area = 2\pi * 3(18)$

Remove bracket

$Area = 2\pi * 3 * 18$

$Area = 2\pi * 54$

$\pi = (22)/(7)$

So, we have:

Area = 2 * (22)/(7) * 54

Area = (2 * 22 * 54)/(7)

Area = (2376)/(7)

Area = 339.42

Hence, the closest is:

$Area = 339.29\ in^2$
