Answer 1

Answer: if i am correct the answer is 75.4

please correct me if i am wrong.

Explanation:

A=2 3.14 r h+2 3.14 r2=2·3.14·2·4+2·3.14·22≈75.39822

Answer 2

Answer: 75.36 square feet

Your teacher may want you to type the number only.

==========================================================

Work Shown:

SA = surface area of a cylinder

SA = 2*pi*r^2 + 2*pi*r*h

SA = 2*3.14*2^2 + 2*3.14*2*4

SA = 75.36

The surface area is roughly 75.36 square feet.
