Below are 4 congruent circles inside a square. The radius of each circle is 3 in. How would you find the area of the shaded region? 

• A

• B

• C

• D

Answer explanation

The radius is 3 so the diameter would be 6 and it is two circles all the way across. So the sides of the square is 12.

12x12 = 144

you can say 6 is the radius for all the circles together
