Chapter 0, Problem 53PO

To determine

The radius of circular area.

Answer to Problem 53PO

  $r=2.5\text{ ft}$

Explanation of Solution

Given:

Circumference $C=16$ ft

Formula used:

Circumference of circle,

  $C=2\pi r$

Where,

  $r=$ Radius

Calculation:

Circumference of circle,

  $\begin{array}{l}C=2\pi r\\ 16=2\times 3.14\times r\\ r=\frac{16}{6.28}\\ r=2.547\text{ ft}\end{array}$

Nearest tenth is 2.5, so the radius of circular area is $\text{2}\text{.5 ft}$ .

Conclusion:

Hence, the radius of circular area is $\text{2}\text{.5 ft}$ .
