A patio in the shape of a semicircle has a diameter of 21 ft. What is the approximate area of the patio, rounded to the nearest square foot? Use 3.14 to approximate pi star times pi.

Answers

The formula of the area of a semi circle is half the area of the circle

$( \pi r^2)/(2)$

Diameter = 21 ft
Radius = $(d)/(2)$ = $(21)/(2)$ = 10.5 ft

Area = $( \pi (10.5)^2)/(2)$
= $(110.25 \pi )/(2)$
= $(110.25 * 3.14)/(2)$ (3.14 as $\pi$ )
= $(346.185)/(2)$
=173.0925 ft² ≈ 173.1 ft² ≈ 173 ft²
To the nearest square foot : 173 ft²
