Question

the perimeter of a circular field is 242 M find the area of the field

Answer 1

Here is your answer

Answer 2

Answer : 4658.5m²

Step-by-step explanation:

Given perimeter of circular field = 242 m

To find : Area

As we know perimeter of circle is given by

$P= 2\pi r\\\\\Rightarrow 242= 2\pi r\\\\\Rightarrow r= \dfrac{242}{2\pi} = \dfrac{242\times 7}{2\times 22} =\dfrac{77}{2}$

Now area if circle is given by

$A= \pi r ^2 = \dfrac{22}{7} \times \dfrac{77}{2} \times \dfrac{77}{2} = 4658.5 m^2$

Hence the area of circular field is 4658.5m²
