There’s two semi-circles with a radius of 2, so it would be 2 x 1/2 x Pi x radius ^2.

Now we need to find the area of the square, which is a^2. The diameter of a circle is double the radius, so we know the sides of the square will equal 4 inches, so 4 x 4.

4 x 4 + 2 x 1/2 x 3.14 x 2^2 should give you your answer. Hope this helps!!

Explanation:

Square= bh

Square= 2×2=

half-circle = 1/2Pi*r×r

half-circle 2 = 1/2Pi*r×r

We would put 1/2 for the half-circle because its half of a circle. And we square it because where finding area. The middle is square, and the two up top is half a circle. Hope that helps :D
