Chapter 8.3, Problem 24PPS

To determine

To calculate: To find two solutions of the equation

Answer to Problem 24PPS

The solutions are $\left(1,6.3\right)$ and $\left(2,12.6\right)$

Explanation of Solution

Given information: Circumference of a circle $C$ with radius of $r$ units is approximately given by linear equation $C\approx 6.3r$

Calculation:

Given that Circumference of a circle $C$ with radius of $r$ units is approximately given by linear equation $C\approx 6.3r$

Finding the two solution of the above equation:

When $r=1$

  $\begin{array}{l}C\approx 6.3\left(1\right)\\ C\approx 6.3\end{array}$

When $r=2$

  $\begin{array}{l}C\approx 6.3\left(2\right)\\ C\approx 12.6\end{array}$

Conclusion:

Hence, solutions are $\left(1,6.3\right)$ and $\left(2,12.6\right)$
