What is the exact volume of the cylinder? A. 5760π in3 B. 2880π in3 C. 480π in3 D. 240π in3

OpenStudy (logan13):

@Mehek14

OpenStudy (xapproachesinfinity):

Cylinder's volume is given by the equation V=pir^2h

OpenStudy (wolf1728):

Here's the formula Volume = π • r² • height

Mehek (mehek14):

same thing again \(πr^2h\\r=12\\h=20\\π*12^2*20\)

OpenStudy (logan13):

12x12x20

Mehek (mehek14):

which is?

OpenStudy (logan13):

2880

OpenStudy (wolf1728):

logan13 don't forget the "pi" in that calculation

Mehek (mehek14):

correct but don't forget π \(2880π\)

Mehek (mehek14):

@wolf1728 π is in the answer

OpenStudy (wolf1728):

but logan13's answer was just 12x12x20
