Icant figure out the volume. i am seriously begging here ! i checked the google calculator but it doesn't have the same answers! explain! !

1. 1296*pi

2. 113.04

3. $3.96

4. 10

Step-by-step explanation:

The equation to find the volume of a cylinder is V=pir^2h or Volumr=pi*radius squared*height

All we need to solve the equation is the height and radius, which it gives us.

Now just insert the values and solve for the equation

V=3.14(12)^2*9

V=3.14*144*9

V=1296*pi

So the answer to the first one  is 1296 multiplied by pi.

Now just repeat for the other questions.

V=3.14*(3)^2*4

v=3.14*9*4

v=3.14*36

v=113.04

The answer for the third one is $3.96

The answer for the fourth one is 10.

Hope this helps!
