Chapter 12.4, Problem 1CE

To determine

To complete: Copy and complete the table for sphere.

Answer to Problem 1CE

Area will be $4\pi$ and volume $\frac{4}{3}\pi$ .

Explanation of Solution

Given information:

The given radius is 1.

Calculation:

The Area of sphere is given by

  $A=4\pi r^2$ and

The Volume is given by

  $V=\frac{4}{3}\pi r^3$ .

Here $r=1$ . Therefore,

Area

  $\begin{array}{l}A=4\pi {\left(1\right)}^2\\ A=4\pi \end{array}$ and

Volume

  $\begin{array}{l}V=\frac{4}{3}\pi {\left(1\right)}^3\\ V=\frac{4}{3}\pi \end{array}$

Hence,

Area will be $4\pi$ and volume $\frac{4}{3}\pi$ .
