Answer:

R=√area/π

Step-by-step explanation:

Area of a circle=πr^2

Divide both sides by the

r^2=area/π

Square root both sides

r=√area/π

Answer:r=√(a/π)

Step-by-step explanation:

Area(a)=π x (radius(r))^2

a=π x r^2

Divide both sides by π

a ➗ π=(πxr^2) ➗ π

a/π=r^2

Take the square root of both sides we get √(a/π)=r

Therefore r=√(a/π)
