The volume of a right circular cone with radius r and height h is V = pir^2h/3. a. Approximate the change in the volume of the cone when the radius changes from r to r and the height changes from h = 4.00 to h = 3.96.
b. Approximate the change in the volume of the cone when the radius changes from r to r and the height changes from h = 10.0 to h = 9.92.
a. The approximate change in volume is dV = . (Type an integer or decimal rounded to two decimal places as needed.)
b. The approximate change in volume is dV = (Type an integer or decimal rounded to two decimal places as needed.)
