Question

What is the area of the lateral surface of the following cylinder?

Answer 1

B is correct answer :)

Answer 2

Surface Area = (2 • π • r²) + (2 • π • r • height)

(2 • π • r²) is surface area of the "ends"

(2 • π • r • height) is lateral area

Lateral Area = 2 * PI * 2 * 7

Lateral Area =28 * PI =

87.9645943005 square inches
Answer is B
