As per data given in the question,

We have to determine the value of radius and circumference of the circle.

As per data,

It is given that,

Area of circle = 154\:m^2

We know that,

Area of circle =\Pi r^2

Circumference of circle =2\Pi r

So, from the formula of area of circle,

We will get,

154 = \Pi r^2\\=> \frac{154}{\Pi} =r^2\\=>r^ 2= \frac{154}{22/7}\\=> r^2 = 49\\=>r = 7\; m

Hence, value of radius will be 7 m.

So, circumference of circle will be

2\Pi r\\=>2 \times \frac{22}{7} \times 7\\=> 44\:m
