The formula to find the volume of a sphere is: V= [tex] \frac{4}{3} \pi r^{3} [/tex] Since the diameter is 18 cm, so the radius is equal to r=18/2 = 9 Now we replace r by it's value, so we get: [tex] \frac{4}{3} \pi 9^{3} [/tex] [tex] \frac{4}{3} \pi 729[/tex] [tex]972 \pi [/tex] And we get approximately [tex]3053.63 cm^{3} [/tex] Hope this Helps :D
