Acylinder has a height 12 and a radius 3.7 what is it’s volume?

The formula for the volume of a cylinder is v = π r² h 
Let's use 3.14 for π. 
Square 3.7 to get 13.69. 
Multiply that by 3.14. 
v = 42.9866 x 12 
Finally, multiply it by 12. 
v = 515.8392

You could also express your answer in terms of pi. 
Square 3.7 to get 13.69. 
Multiply it by 12. 164.28 is what you get.
v = 164.28π 

Hope this helps!
