How much greater is the area of a square with a side length of 9 inches than the area of a circle with a radius of 3 inches?

The area of the square is 81 sq in, and the area of the circule is (3.14)(3 in)^2, or approx 3.14(9) sq in, or approx  28.27 sq in.

Subtract:  81 sq in - 28.27 sq in = approx. 52.73 sq in.

The difference is 52.73 sq in; the square is larger, the circle smaller.

I’ll you if you answer my questions!

31 is prime. and it’s prime factorization is just 31.
