The formula for volume of a sphere is 3/4x(pi)x(r)^3. Where r is the radius of the sphere. V = 3/4x(3.142)x(7)^3 = 1437 mm^3

Answer: 1436 cubic mm

Explanation:

We know the volume of sphere is given by :-

$\text{Volume}=(4)/(3)\pi r^3$

Given : The radius of the sphere = 7 mm

Therefore, the volume of the sphere is given by :-

$\text{Volume}=(4)/(3)(3.14)(7)^3\\\\\Rightarrow\ \text{Volume}=1436.02666\approx1436\ mm^3$

Hence, the volume of the sphere = 1436 cubic mm.
