The radius of a spherical balloon is measured as 20 inches, with a possible error of 0.01 inch. Use differentials to approximate the maximum possible error in calculating the following:

(a) the possible propagated error in computing the volume of the sphere.
(b) the possible propagated error in computing the surface area of the sphere.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
