Chapter 11, Problem 19MCQ

To determine

To find: The radius of the circle.

Answer to Problem 19MCQ

The radius of the circle is $5.75m$ .

Explanation of Solution

Given Information: Given area is $104square\mathrm{meters}$ .

Given area is $104square\mathrm{meters}$ .

Area of circle $=\pi r^2$ .

  $\begin{array}{l}\pi r^2=104\\ \frac{22}{7}{r}^2=104\\ r^2=104\times \frac{7}{22}\\ r=\sqrt{104\times \frac{7}{22}}\\ r=5.75m\end{array}$

Thus, the radius of the circle is $5.75m$ .
