A spherical ball hss a diameter of 45cm. Workout the volume of the ball
Well, the formula to find the volume of a sphere is V = ⁴⁄₃(pi)*r3
The radius would be half of the diameter, so radius = 45/2 = 22.5
Now we have
V = 4/3(pi)*22.53
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 cm3
