Question

The radius of a semi-circle measures 5 units. Find its area.

Answer 1

Answer:

≈39.27 units

Step-by-step explanation:

To find the area of a semi circle, you use the formula for finding the area of a circle, which is $\pi$$r^{2}$, and then you divide that by 2 since it is half of a circle.

In this case, $\pi$$(5)^{2}$ ≈ 78.54

$\frac{78.54}{2}$ = 39.27
