Answer to Question #5529 in Geometry for jennifer
Find the total surface area, in square inches, of a cylinder with a radius r = 8 in. and height h = 5 in.
The total surface area consists of cilinder basis area
S1 = 2*pi*R^2
and cilinder lateral surface area
S2 = 2*pi*R*H
S = S1 + S2 = 2*pi*R^2 + 2*pi*R*H = 2*pi*8^2 + 2*pi*8*5 ≈ 653.4513 square inches.
