Question

Find the area of a circle with a circumferenceof 261 feet.

Answer 1

It is given that Circumference of circle is 26П feet

The expression for the Circumference of circle is 2Пr.

So,

`\begin{gathered} 2\Pi r=26\Pi \\ r=(26\Pi)/(2\Pi) \\ r=13 \end{gathered}`

Radius of the circle is 13 feet

The expression for the area of circle is ПRadius²

`\begin{gathered} \text{Area of circle =}\Pi* r^2^{} \\ \text{Area of circle=3.14}*13*13 \\ \text{Area of circle = 530}.93\text{ f}eet^2 \end{gathered}`

Answer: 530.9
