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
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!!
If you have a fraction, take one number and put a different number on top or underneath, for example if you have 2 cats and 3 dogs, the ratio from cats to dogs would be 2:3 but if you did 2 cats to the total number of animals, you would add 2 and 3 and get 5, so the ratio would be 2:5.
