Question 58547
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.
V=(pi)r^2h
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]
=121/28.27433
=4.2795
-------------------
c) Graph this function.
{{{graph(300,200,-10,20,-10,10,121/(3.14159x^2))}}}
