Question

What is the diameter of a hemisphere with a volume of 74466\text{ cm}^3,74466 cm 3 , to the nearest tenth of a centimeter?.

Answer 1

Below

Explanation:

Volume of an ENTIRE sphere = 4/3 pi r^3

a HEMI-sphere is 1/2 of this : 1/2 * 4/3 pi r^3 = 2/3 pi r^3

74466 cm^3 = 2/3 pi r^3

shows r = 32.88 cm diameter is twice this amount = ~ 65.8 cm
