Question 84044: Help!! I'm math stupid! I have no idea how to solove this problem, unforutnately I'm running on a dealine. Can anyone assist me?
The volume of a can (like tin can) is given by V = πr2h where r is the radius of the can 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 can in 3 centimeters? Round your answer to the hundredth's place.
Answer:
Show work in this space.

c) Graph this function.

a)
To solve for h divide both sides by
So h equals

Since its a 121 cubic centimeter can h equals

b)To find out the height if the radius is 3 cm, just plug in 3 for r and 121 for V of the 100 cubic centimeter can (this is given above)
Let r=3,V=121

Approximately

So the height of the can is about 4.28 cm

c)
To graph this function, let r be x and h be y.
