Question

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

Answer 1

≈39.27 units

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

`(78.54)/(2)` = 39.27
