Question 458817: The radii of four spheres are 3/2m, 5/2m, 7/2m, and 9/2m.
a. Find the volume of each sphere in terms of pi.
b. Find the surface area of each sphere in terms of pi.
Answer for a. 9pi/2 m3, 125pi/6 m3, 343pi/6 m3, 243/2 m3
Answer for b. 9pi m2, 25 pi m2, 49pi m2, 81pi m2.
I would like to know step of solve. Thanks for your time.
