Question

Find the area of the Composite Shape:

Please Help! ​

Answer 1

151.27 cm^2

Explanation:

We can tell that the radius of the semicircle is 5 cm. This is because the diameter is 10 cm (16 cm - 6 cm).

Area of Circle:

A(c) = π
`r^(2)`/2 = π(5 cm)^2/2 = 25π cm^2/2 = 78.54 cm^2/2 = 39.27 cm^2

Area of Rectangle:

A(r) = 16 cm * 7 cm = 112 cm^2

A = A(c) + A(r) = 39.27 cm^2 + 112 cm^2 = 151.27 cm^2
