Well, the formula to find the volume of a sphere is **V = ⁴⁄₃(pi)*r ^{3}**

The radius would be half of the diameter, so radius = 45/2 = 22.5

Now we have

V = 4/3(pi)*22.5^{3}

V=4/3(pi)*11390.625

v = 4/3*11390.625*(pi)

V = 15187.5(pi)

$${\mathtt{15\,187.5}}{cm}{\mathtt{\,\times\,}}{\mathtt{\pi}} = {\mathtt{47\,712.938\: \!426\: \!394\: \!984\: \!809\: \!2}}{cm}$$

Or, rounded to the nearest whole number:

**47,713 cm ^{3}**
