SOLUTION: a^2 + 12^2 = 16^2 Square the 12 and 16. Then subtract and take the square root. You will then have the other side of the rectangle as well as the diameter of the circle.

Question 1162520: a^2 + 12^2 = 16^2 Square the 12 and 16. Then subtract and take the square root.
You will then have the other side of the rectangle as well as the diameter of the circle. You will need to divide it by 2 to get the radius.
Area of rectangle - Area of circle
LW - pi r^2
a^2 = 112 From here, take the square root of both sides. Use the square root button on your calculator. Divide this value by 2 to get the radius.
Then, plug into A = pi r^2 to get the area of the circle. This is also one of the sides of the rectangle, and the other side is 12. Use A = lw to find the area. Last, subtract the two areas. please help me I am confused.???
