Chapter 12.6, Problem 2PSA

To determine

To find: The Volume and Surface area of the sphere having radius 5 units.

Answer to Problem 2PSA

The volume and the surface area would be

  $\begin{array}{l}(V)=523.6{\text{ unit}}^3\\ S.A.=314.16{\text{ unit}}^2\end{array}$

Explanation of Solution

Given info:

  $r=5\text{ units}$

Formula used:

  $V=\frac{4}{3}\pi r^3$

  $S.A=4\pi r^2$

Calculation:

Substituting the given values, we get

  $\begin{array}{l}$ V=\frac{4}{3}\pi {(5)}^3$V=523.6{\text{ unit}}^3\\ S.A.=4\pi {(5)}^2\\ S.A.=314.16{\text{ unit}}^2\end{array}$
