Assuming that the area is what you mean by "50 sq meter," and since the area formula = (pi) * radius squared, divide 50 by pi and take the square root.
Radius = a little less than 4 meters

The formula for area of a circle is pi*r^2, where pi is 3.14159 and r is the radius. Since you have the area and not the radius, rewrite A = pi*r^2 as r = sqrt(A/pi), and there's your solution. Just divide the given area of 50 m^2 by pi, and take the square root.

AREA OF A CIRCLE=Pi*r^2=3.14*r*r
50 sq. meter=3.14*r^
r^=50/3.14
r=3.9887meter

Area = pi * r squared. So the radius = the square root of the Area divided by pi.

Area Formula of a circle is
A = πr²
solving for radius
a/π= πr² /π
dividing both sides of the equation by π
a/π = r²
- - - - - - - - - - - - - - - - - - - - -
50/3.141592544 = r²
√15.91549431 = r²
3.989422804 = r
3.99 = r (rounded up to two decimal places)
The radius is 3.99 Meters

AREA OF CIRCLE = Pi*r^2
where pi = 3.14 or 22/7
so r^=50/3.14
or
r^ = 50*7/22
equals to (=) 3.9887

you divide 50 by 3,14 and that you extract the square root
it's approximately 4 meters
