Question

Find the area of the figures below, composed of a rectangle and a semicircle. The radius of the circle is shown. Round to the nearest tenth place

Answer 1

50.3 square units

Explanation:

area of rectangle: 11 x twice the radius

radius = 2

A(rect): = 11(4) = 44 sq units

A (semi-circle) = (π·r²) / 2

A = 4π / 2 = 2π = 6.28 sq units

44.0 + 6.28 = 50.28
