Question

The area of a circle is found with the formula A = ?, where y represents 3.14. If a tile artist

Answer 1

The approximate radius of the circle in feet is 14.5

Solution:

Given, a tile artist is placing tiles in a circular mosaic pattern and the area of the circle is 658 square feet,

We have to find what is the approximate radius of the circle in feet?

The area of a circle is found with the formula $\mathrm{A}=\mathrm{yr}^{2}$

where "y" represents 3.14 and r is radius. So now, according to given information,

$\begin{array}{l}{y r^{2}=658} \\\\ {\rightarrow 3.14 \times r^{2}=658} \\\\ {\rightarrow r^{2}=209.55} \\\\ {\rightarrow r=14.4759}\end{array}$

Hence, the radius of the given circle is 14.5 feet approximately
