Question 1199296
.
A circle has an area of approximately 615.75 in2.
What is the circumference of the circle? Use 3.14 for π.
~~~~~~~~~~~~~~~~


<pre>
From  {{{pi*r^2}}} = 615.75 in^2 find


    {{{r^2}} = {{{615.75/3.14}}} = 196.0987

    r = {{{sqrt(196.09870)}}} = 14 inches (rounded).


Next calculate the circumference  S = {{{2*pi*r}}} = 2*3.14*14  inches.


To get the value, use your calculator.

Solved.
