Answer:
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!
