Question 68232: I really need help with this, i cant remember how to do it, and i need it done by tonight. I would really appreciate your help

) The volume of a cylinder (think about the volume of a can) is given by V = πr2h where r is the radius of the cylinder and h is the height of the cylinder. Suppose the volume of the can is 121 cubic centimeters.
a) Write h as a function of r. Keep "π" in the function's equation.
Answer:
Show work in this space.



b) What is the measurement of the height if the radius of the cylinder is 3 centimeters? Round your answer to the hundredth's place.
Answer:
Show work in this space.



c) Graph this function.

You can put this solution on YOUR website!
V = 2πrh
121 = 2πrh
h=121/2πr
h=60.5/πr
r=3
h=60.5/3π
h=6.42
