Question 50936
Area of a circle = (pi)(r^2) [The formula for the area of a circle]
25m^2=(pi)(r^2) [Plug-in the values]
25/pi=(pi)(r^2)/(pi) [Solve for the radius (r)]
25/pi=r^2 
{{{(sqrt(25/pi))=(sqrt(r^2)) )}}}
2.820947=r [Round to the nearest 100th place]
2.82=r
.
Check that (r=2.82) by plugging it back into the original equation:
Area of a circle = (pi)(r^2)
25=(pi)(2.82^2)
25 is equivelent to 24.9832 [Close enough]
