Question

What percent of the surface area of the ottoman is green not including the bottom .The radius of the ottoman is 22 in and the cushion is 6 in and the green is 10 in

Answer 1

37%

Explanation:

Surface area of a cylinder = πr² + 2πrh

With r = 22 and h = (6 + 10) = 16

Area = π * 22² + 2 * π * 22 * 16

Area = 1520.728 + 2211.968

Area = 3732.696 in²

Percentage of green = surface area of green ÷ total surface area

Surface area of green = 2πrh

Surface area of green = 2 * π * 22 * 10

Surface area of green = 1382.48

Percentage of green = 1382.48 / 3732.696 * 100%

Percentage of green = 37%
