Find the area of the semicircle. Round your answer to the nearest hundredth.<br> PLEASEE HELPP

trapecia [35]

Answer:

Area of semicircle = 226.08 in²

Step-by-step explanation:

Diameter of semicircle = 24 in

We need to find area of semicircle.

The formula used to find area of semicircle is: $Area=\frac{\pi r^2}{2}$

First we will find radius

We know that: radius = diameter/2 = 24/2 = 12

Now, finding area

$Area=\frac{\pi r^2}{2}\\Area=\frac{3.14\times (12)^2}{2}\\Area=\frac{452.16}{2}\\Area=226.08\:in^2$

So, Area of semicircle = 226.08 in²
