circle radius of 5 on top of a 11*11 rectangle

Question

what is the area of the rectangle if the circle was a hole.

Answer 1

The area of the rectangle (a square, since it is 11x11) is 11*11= 121 sq units.

Assuming that you are asking what the area is if you cut out a hole with radius 5,

the area is 121 - π*5² = 121 - 25π, or approx. 42.46 sq units.
