Question

What is the lateral area of a right cylinder if the radius of the base is 12 mm and the altitude of the cylinder is 5 times the base radius? Round your answer to the nearest whole number.

Answer 1

Lateral Area of a cylinder is ; 2πR.H

R=12 mm and H= 15 mm


Then LATERAL area = 2π(12)(15) =48π ≈ 150 mm²
