The radius will be 7.25cm
The circumference will be about 45.55
The area will be about 165.13
#21 the answer is does √ 9^2 + 2^2
a^2 + b^2 = c^2
9^2 + 2^2 = c^2
√ 9^2 + 2^2 = √ c^2
The answer is none because the square cannot be rotated into a cone or a cylinder. The square would need some sort of a circle to be made into those.
I believe it’s X = 4
So 4 would be the answer
