Question

What’s the area of a semi circle

Answer 1

14.13

Explanation:

Since we know the area of a circle is
`\pi r^2`, we just need to divide it by 2 to get the semicircle's area (
`(\pi r^2)/(2)` )

We know the radius is equal to half of the diameter, or in this case 3, and we're approximating pi to 3.14, so we just substitute on the formula:


`((3.14)(3)^2)/(2) = ((3.14)(9))/(2) = (28.26)/(2) = 14.13`
