Question

there's a circle inside of a square like this: donlehmanjrcom/Tai%20Chi/Tai%20Chi%20Newsletters/excerpts11%20images/image001.png (add the period before the com)
the circle has a radius of 2 in and an area of 12.56 in^2
how do i find the area of the space outside the circle (the square)? there's no measurements for the square so i'm confused.

Answer 1

Isn't the diameter of the circle the same as one side of the square?

Answer 2

so
2(2) = 4
4 * 4 = 8
12.56 - 8 = 4.56 in^2 is the area?

Answer 3

4 * 4 does not = 8

Answer 4

oops
2(2) = 4
4 * 4 = 16
16 - 12.56 = 3.44 in^2

Answer 5

Yes, you're right.
