Question

Find the area of the figure. Round your answer to the nearest hundredth, if necessary 8cm

Answer 1

Explanation:

The figure is a semi-circle.

Area of a circle is = π
`r^(2)`

So area of a SEMI-circle is 1/2π
`r^(2)`

Given:

d = 8cm -> r = d/2 = 8/2 = 4cm

Area =
`(1)/(2)`π(4)^2 = 25.13 cm^2
