Homework Statement
Use the formula V = (1/3)pi r2(h) for the volume of a right circular cylinder to find
a. the average rate at which the volume of a right circular cylinder changes with the radius r as r increases from 3 cm to 6 cm.
b. the instantaneous rate at which the volume of the right circular cylinder changes with r when r = 6 cm.
I tried to solve it at home and I arrived at the answers:
a. 3(pi)(h)
b. 4(pi)(h)
Are my answers correct?
thanks
