Amanufacture drills a hole through the center of a metal sphere of radius R. The hole has a radius r. If R= 6, what value of r will produce a ring whose volume is exactly half the volume of the sphere? A r=_ will prduce a ring with a radius equal to half that of the orginal sphere.

A manufacturer drills a hole through the center of a metal sphere of radius R. The hole has a radius r. Find the volume of the resulting ring. 65. For the metal sphere in Exercise 64, let R = 5. Wha t value of r will produce a ring whose volume is exactly half the volume of the sphere? 66. The solid shown in the figure has cross sections .

Step-by-step explanation:

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
