I have a hunch that you mean a circle, not a square. Squares do not have radii.
If so:
A = pi r^2
= (22/7)(36)(2)
about 6*36 or 216
On the other hand if it is a square with side (not radius) = 6 sqrt 2
then
36*2 = 72 so B
Find the area of a square with the radius 6√2 m. Round to the nearest whole number.
A)51m^2
B)72m^2
C)144m^2
D)196m^2
My answer is B.

I just found out that a square can have a radius. But I don't know how to solve this problem.

Interesting article, but since when does √72 = 2.913 ??
2.913 = √√72
2.913 = √√72
well, the distance from center to corner by that definition is 6 sqrt 2
so the diagonal of the square is 12 sqrt 2
so the side of the square is 12
so the area is 144
so the diagonal of the square is 12 sqrt 2
so the side of the square is 12
so the area is 144
