Question 67628: Please help me with this!
1) 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 "" 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.

1) The volume of a cylinder (think about the volume of a can) is given by V = πr^2h 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 "" in the function's equation.
Answer:
Show work in this space.
h=V/[pi r^2]
h=121/[pi r^2]
-------------------------


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.
h=121/[pi 3^2]
h=121/9pi
h=42.24
---------------

c) Graph this function.[h=121/(9r^2)]
Show graph here.
