pi * radius^2
OpenStudy (anonymous):
radius
OpenStudy (solomonzelman):
\[\huge {r^2π=A}\]
OpenStudy (solomonzelman):
A is area.

I know, I was just typing to give it a s a formula with math-variables.
OpenStudy (solomonzelman):
Do you need it in \[\huge {π}\] or as an approximate value?
OpenStudy (anonymous):
approximate value
OpenStudy (solomonzelman):
\[\huge { π = 3.14}\]
and what is your radius?
OpenStudy (anonymous):
7

So plug the numbers into the formula\[\huge {(7)^2 \times 3.14=?} \]
OpenStudy (anonymous):
so id be 153.86?
OpenStudy (anonymous):
multiply the base length
OpenStudy (solomonzelman):
@Precious56, you are right, for Volume, but the user just asked for the base.
@vanessat, yes, you got the correct answer!
Do you need more help?
OpenStudy (anonymous):

Surface area?
OpenStudy (solomonzelman):
\[SA = πr^2 + πrl\]
OpenStudy (anonymous):
just the surface area so use this SA = πr^2 + πrl
