Question

A cylinder has a radius of 30.8 centimeters and height of 20.5 centimeters. Which measurement is closest to the lateral surface area of the cylinder in square centimeters

Answer 1

The answer to your question is 9923 cm²

Explanation:

Data

radius = 30.8 cm

height = 20.5 cm

Surface area = ?

Process

1.- Write the formula to calculate the surface area of a cylinder

SA = 2πr² + 2πrh

2.- Substitution

π = 3.14

SA = 2(3.14)(30.8)² + 2(3.14)(30.8)(20.5)

3.- Simplification

SA = 5957.459 + 3965.192

4.- Result

SA = 9922.65 cm² or SA = 9923 cm²
