Question

Which of the following formulas would find the lateral area of a right cylinder with height equal to h and r as the radius?

A. LA = 2r2
B. LA = 2r
C. LA = 2rh
D. LA = 2r2 + 2rh

Answer 1

Answer: LA=2pie rh

Explanation:

Answer 2

Lateral surface area of right cylinder = 2 * π * radius * height.

Explanation:

Given : A right cylinder with height equal to h and r as the radius.

To find : Which of the following formulas would find the lateral area.

Solution : We have given that height of cylinder = h

radius of cylinder = r.

Lateral surface area of right cylinder = 2 * π * radius * height .

Formula for LA = 2πrh.

Therefore, Lateral surface area of right cylinder = 2 * π * radius * height.
