Question

What is the area of this composite figure

Answer 1

Answer:

Area of Triangle = 1/2 bh

                    A = 1/2 (16 cm x 10 cm)

                   A = 160 cm2/2

                    A = 80 square cm

Area of Circle = $\pi$d2/4

                  A = 3.14 x (16 cm)2 / 4

                  A = 3.14 x 256 cm2 / 4

                 A = 803.84 cm2 / 4

                 A = 200.96 cm2

        Area of Half Circle = 200.96 cm2 / 2

                 A = 100.48

Composite Figure = Area of Triangle + Area of half Circle

Area of Composite Figure = 80 cm2 + 100.48 cm2

Area of Composite Figure = 180.48 cm2
