Answer 3

Find the area of the circle and subtract it from the area of the square.

Answer 4

Isn'the area of the circle 28?

Answer 5

That is the length of one side of the square. It appears to me that the diameter of the circle would be 28, however.

Answer 6

however.....?

Answer 7

I meant instead of the area, it's the diameter.

Answer 8

So radius=14

Answer 9

so 3.14 x 14 or 3.14 x 28 ?

Answer 10

Area of a circle is \[\Large A=\Large \pi * \Large r^2\]
