Volume and Surface Area Test Review

Front

What is the formula for the surface area of a cylinder?

Back

Surface Area = 2πr(h + r), where r is the radius and h is the height.

How do you calculate the surface area of a cylinder with a height of 10 ft and a radius of 3 ft?

Back

Surface Area = 2π(3)(10 + 3) = 2π(3)(13) = 78π ft².

Front

What is the surface area of a cylinder with a radius of 6.4 inches and a height of 10 inches?

Back

Surface Area = 2π(6.4)(10 + 6.4) = 2π(6.4)(16.4) = 209.92π in².
