967.12 in

Explanation:

the formula for the area (surface area) of a cylinder is: A=2πrh+2πr2

to solve we need to determine the values

R= radius = half the diameter = 14/2 =7

D= diameter =14inches

H= height= 15 inches

plug in

A=2πrh+2πr2 = A=2π(
(d)/(2) )h+2π(
(d)/(2) )^2

= 2
$\pi$ (
(14)/(2) )(15) + 2
$\pi$ (
)^2

= 2
$\pi$ (7)(15) + 2
$\pi$ (7)^2

=
$\pi$ ((2x7x15)+(2x7^2))

=
$\pi$ (210+98)

=
$308\pi$
