Question

If the diameter of the sphere is d then volume is

Answer 1

volume of sphere = 4/3pier^3

where r = d/2

so

4/3 22/7× (d/2)^3

88d^3 / 56

Answer 2

$volume \: of \: sphere = \frac{4}{3} \times \pi \times r {}^{3 } \\ radius \: r = \frac{diameter}{2} \\ r = \frac{d}{2} \\ v = \frac{4}{3 } \pi \times \frac{d {}^{3} }{8}$
