Hey please help ! Will mark the brainliest will be geniune no links some expert :(

Answer 1

Answer:

3rd option

Step-by-step explanation:

The area (A) of a semicircle is calculated as

A = $\frac{1}{2}$ πr² ( r is the radius )

Here diameter = 44, so r = 44÷ 2 = 22

Then

A = $\frac{1}{2}$ π × 22² = $\frac{\pi (22^2)}{2}$

Answer 2

Answer:

C

Step-by-step explanation:

To solve for the area of a circle, you use the equation pi*r^2.

To solve for a half-circle, you divide by two.

Hope this helped! :)
