Question

Need help for school please

Answer 1

A ≈ 153.1 units²

Explanation:

area (A) of rectangle is

A = length × breadth = 16 × 8 = 128 units²

The diameter of the circle is 8 , then radius = 8 ÷ 2 = 4

area of semicircle =
`(1)/(2)` × πr² ( r is the radius )

=
`(1)/(2)` × π × 4²

=
`(1)/(2)` × π × 16

= 8π

Then area of figure = 128 + 8π ≈ 153.1 units² ( to the nearest tenth )
