I meant the circumference of the regular circle right through the middle. \[2 \pi r\]

I made an error in the explanation. It should have been: No, because the circumference is given by\[2\pi r\]and the surface area is given by\[4πr^2\]The circumference squared would be \[4\pi^2 r^2\]

Area is measured in square units. Volume is measured in cubic units. Surface Area square units.
