To determine

To find : Distance in $10$ revolutions.

Answer to Problem 20IP

  $\text{2514}\text{feet}$

Explanation of Solution

Given information :

The given information is, Diameter = $80$ feet.

Formula Used:

Circumference = $\pi d$

Calculation :

Distance covered in one revolution = $\frac{22}{7}\times 80$ feet

  $\Rightarrow$ Distance covered in $10$ revolutions.

  $\begin{array}{l}=\frac{22}{7}\times 80\times 10\text{ feet}\\ =2514.28\text{feet}\\ \approx 2514\text{feet}\end{array}$
