the formula to find the volume of a cylinder is \[\Pi r ^{2}h\] so just plug in the numbers to solve
OpenStudy (anonymous):
A. 60π cm^3 B. 300π cm^3 C. 720π cm^3 D. 1200π cm^3
OpenStudy (egbeach):
\[5^{2}\times12\Pi \]

942.48cm³ this is the answer is got but doesn't seem to be an answer choice.

Volume of cylinder = pie * r * r * h

i got an diffferent answer... 25X12 is what?
OpenStudy (anonymous):
300
OpenStudy (princeharryyy):
300*3.14 = 942

it's correct @pinkbubbles it is 942
OpenStudy (anonymous):
300 is but not 942
OpenStudy (egbeach):
the answers are in the form of pi. dont mulitply the pi out into your answer. 25x12=300. 300pi will be the answer
OpenStudy (princeharryyy):
then they would have written 300*pie
OpenStudy (anonymous):
Okay Thank You! @egbeach and @princeharryyy

they did... look at choice B
OpenStudy (princeharryyy):
and wouldn't have actually mutiplied by the value of pie in the expression though both of the answers are right
