Do you know how to find the radius of the circle in your picture?

Answer 5

no

Answer 6

is the answer : A= 4pi - 8

Answer 7

From the diagram we can see that the diagonal is equal to 2xradius

Answer 8

Hint: You must use pythag. theorem.

Answer 9

Hence
\[πr^2-s^2\]
\[=π(2)^2-{2√2}^2\]
\[=4π-8\]
