Question

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

Answer 1

radius of base: 12mm
height: 60mm

A=2$\pi$rh
A=2$\pi$(12)(60)
A=2(720)$\pi$
A=1440$\pi$
A= approximately 4523.89

The lateral area of a right cylinder if the base is 12mm and the altitude is 5 times the base's radius is 4524mm^2
