Question 50936
Remember that the area of a circle is given by:
{{{A = (pi)r^2}}} To solve for r (radius), divide both sides by {{{(pi)}}}
{{{A/(pi) = r^2}}} Now take the square root of both sides.
{{{sqrt(A/(pi)) = r}}}

If A = 25 sq. meters, and {{{(pi)}}} = 3.14 (Approximately)
{{{r = sqrt(25/3.14)}}}
{{{r = 2.821}}}meters, rounded to the nearest thousandth.
