The volume of a right circular cone with radius r and height h is v=(πr^2h)/3.
a. approximate the change in the volume of the cone when the radius changes from r=5.8 to r=6.3 and the height changes from h=4.40 to h=4.37.
b. approximate the change in the volume of the cone when the radius changes from r=5.18 to r=5.16 and the height changes from h=12.0 to h=11.93.
