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(
(14)/(2))^2

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

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

=
\pi(210+98)

=
308\pi
