Question

# 8 Q please solve the equation

Answer 1

The area of lateral surface of cylinder = 2π r h
r ⇒⇒ radius
h ⇒⇒ height

r = 15.1 in   and   h = 12.8 in
The area of lateral surface of cylinder = 2 *π * 15.1 * 12.8 = 1,214.414 in²
To the nearest square unit = 1,214 in²

The third choice is the answer.

Answer 2

The lateral area is given by 
   A = 2πrh
   A = 2π(15.1 in)(12.8 in)
   A ≈ 1214 in²
