The formula for the volume of a sphere is Upper V equals four thirds pi r cubedV=
4/3πr3​, where r is the radius of the sphere. The steel ball to the right is in the shape of a sphere and has a diameter of 3030 millimeters.
a. Find the exact volume of the sphere.
b. Find a​ 2-decimal-place approximation for the volume.

[tex]\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\quad \begin{cases} r=radius=\frac{diameter}{2}\\ d=diameter\\ ----------\\ d=10\\ r=5 \end{cases}\implies V=\cfrac{4\pi \cdot 5^3}{3}[/tex]


now, that rounded to 2 decimals is just 523.60
