Area of a circle is 80 cm². Work out the circumference of the circle. Can someone please help. And tell me how you did it please.

The circumference of circle is: 31.714 cm

Step-by-step explanation:

Let C be the circumference of the circle

And A be the area of circle

It is given that:

We have to find the radius first so that it can be used to find the circumference

The area of circle is given by the formula:

Putting the value of area

Taking square root on both sides

Now

Putting the value of radius

Hence,

The circumference of circle is: 31.714 cm

the answer to the question is a  

it has the same slope and the same y-intercept.
