A = pi * r^2
divide A by pi
A/pi = r^2
take square root each side and discard the negative answer
sqrt(A/pi) = r

Yes Area of a circle = pi*radius2
How do you find the volume of a cylinder when you know the circumference and height?
Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).Solve for the radius first, then use the formula for the volume of a cylinder (volume = base x height = pi x radius2 x height).
What is the formula of finding the surface area of a circle?
This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.
What is the formula to calculate the height of a cylinder Volume equals 14137cm3 Radius equals 6cm What is the Height of the Cylinder?
volume = pi*radius2*height Rearrange the formula by dividing all terms by pi*radius2: height = volume/pi*radius2 height = 14137/pi*36 = 124.9985239 cm. Therefore: height = 125 cm to the nearest cm.

How do you find the radius when you only have area of a circle?
Use the formula area = pi x radius2. If you replace everything you know, you can solve for the radius.
What is the radius of a circle with an area of 78.5 square inches?
pi*radius2 = area pi*radius2 = 78.5 radius2 = 78.5/pi radius2 = 24.98732607 radius = square root of 24.98732607 = 4.998732446 inches The radius is 5 inches correct to one significant figure.
How do you find the radius of a circle if you already know the area?
The area of a circle equals pi times the radius squared (A = pi*radius2) where pi is 3.1416 So the radius is the square root of the area divided by 3.1416
What is the formula to calculate the height of a cylinder Volume equals 14137cm3 Radius equals 6cm What is the Height of the Cylinder?
volume = pi*radius2*height Rearrange the formula by dividing all terms by pi*radius2: height = volume/pi*radius2 height = 14137/pi*36 = 124.9985239 cm. Therefore: height = 125 cm to the nearest cm.
Find diameter when you only have area of a circle?
pi*radius2 = area of a circle radius2 = area/pi radius = square root of (area/pi) diameter = 2*radius
What is the radius of a circle that has an area of 6644.24?
As area = pi * radius2, the radius is given by radius = sqrt(area /pi) radius = sqrt(6644.24 / pi) = 46 with pi = 3.14
What is total surface area of solid hemisphere of radius r?
It is in square units: (2*pi*radius2)+(pi*radius2)
How do you figure pi radius of a circle?
The area of any circle = pi*radius2
