Related to surface area and volume.
Asked by | 13th May, 2010, 03:22: PM
Surface area of sphere = 4πR2 = 616
R = (616x7/(22x4)) = 7 cm.
Volume of sphere = 4πR3/3 = 4312/3.
The volume of the sphere will now be the volume of cone,
Volume of cone = πR2H/3 = 4312/3
R = (4312x7/(22x28)) = 7 cm.
Hence the diameter of cone base is 7x2 = 14 cm.
