Half the square root of the square radius equals the circle radius.
it is square root of the area divided by pi
Radius is the square root of (area divided by pi).
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Divide the area by pi and then square root it this will give the radius of the circle.
Half the square root of the square radius equals the circle radius.
Area of circle: 18pi Radius of circle: square root of 18 = 3 times square root of 2 Using Pythagoras' theorem each side of the square is 6 units in length
it is square root of the area divided by pi
take off the circle at the bottom, and mold it into a square.
Radius is the square root of (area divided by pi).
divide the square feet by pi that gives you the radius squared find the square root and get the radius
Divide the 81 pi by pi, then square root it. (Use the formula for area of circle, which gives 81pi=pi*radius squared, but rearrange to find the radius). i.e. it's the square root of 81
Radius of circle is the square root of 154/pi = 7 units rounded
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Divide the area by pi and then square root it this will give the radius of the circle.
Area of a circle equals pi r2 Therefore the radius of a circle equals the square root of (area divided by pi).
