Question 33159This question is from textbook college algebra
: I have some algebra that I need help with.
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 100 cubic centimeters.
a)Write h as a function of r.
b)What is the measurement of the height if the radius of the cylinder is 2 centimeters?

c)Graph this function.

The volume of the cylinder is V= 2*pi*r*h
where r is the radius of the cylinder ,h is the height..

the value of"h" as a function of "r" is got by
just rearranging the formula for volume.
therefore h = v/(2*pi*r)
when r = 2cm and v= 100 cm^3,
h = 100/(2*3.14*2) (pi= 3.14)
= 7.96 cm
