Question

How do you solve this

Answer 1

To find the surface area, use the formula for surface area of a cylinder:

S.A. = 2πrh + 2πr², where r is the radius and h is the height.

The radius and height are given as follows.

r = 5

h = 16

Plug these values into the formula and solve to find the S.A.

S.A. = 2πrh + 2πr²

S.A. = 2π(5)(16) + 2π(5)²

S.A. = 2π80 + 2π25

S.A. = 160π + 50π

S.A. = 210π

Since we are leaving our answer in terms of pi, we don't need to do anything more.

Answer:

S.A. = 210π cm²
