The last 2 questions please help me help me please I need help

3. 12.5π + 100

6. 25π + 250

Step-by-step explanation:

3. So you can first calculate the area of the square, which is 100.

Then you have to calculate the semicircle.

You can see that the diameter is 10.

The radius is 5.

The area of the semicircle is 12.5π

Total area is 12.5π + 100

6. You have a one rectangle and two semicircles.

You can calculate the area of the semicircles first.

25π

Then, you have to see how much the width of the rectangle is.

You can see that the total width is 35, and the radius of each semicircle is 5.

35 - 5 - 5 = 25

The width is 25 so the area of the rectangle is 250.

The total is 25π + 250.

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
