Question

HELP ME PLAES JUST PLEASE AND THANK YOU

Answer 1

If that were a FULL circle then the area is PI * radius^2=

3.14159265 * 4 * 4 = 50.2654824

Since that is a semi-circle then the area is half of that or 25.1327412

Explanation:

Answer 2

25.12 units^2

Explanation:

The area of a semicircle is 1/2 the area of a full circle. The area of a full circle is pi*r^2, so the area of a semicircle is 1/2*pi*r^2.

1/2*(3.14)*4^2=0.5*3.14*16=25.12

Therefore, 25.12 units^2

I hope this helped and have a good rest of your day!
