The volume of a cone is given by 
, where r is the radius of the base and h is the height. Assume the height is measured to be h = 6.00 ± 0.01 cm and the radius is r = 5.00 ± 0.02 cm.
a. Estimate the volume of the cone, and find the uncertainty in the estimate. b. Which would provide a greater reduction in the uncertainty in V: reducing the uncertainty in h to 0.005 cm or reducing the uncertainty in r to 0.01 cm?
