Question

Just wondering. Is the surface area of a sphere the circumference of the sphere squared?

Answer 1

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

Answer 2

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 \[4\pi^2 r^2\]

Answer 3

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

Answer 4

How do you derive the surface area of a circle?

Answer 5

calculus

Answer 6

you can do it with a double or tripple integral

Answer 7

and Im sure many other ways
