Question

A cylinder has a base area of 20.7 in2 and a lateral area of 25.3 in2. What is the surface area of the cylinder? Use 3.14 for π and round to the nearest tenth, if needed.

Answer 1

Given that a cylinder has a base area of 20.7 in^2 and lateral area of 25.3 in^2. The surface of the cylinder will be given by:
SA=πr^2+πrl
where
πr^2=base area=20.7 in^2
πrl=lateral area=25.3 in^2
SA=(base area)+(lateral area)
SA=20.7+25.3
SA=52.3 in^2
