Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.

The radius squared. The radius is half of the diameter

Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.

Yes, it is. Hint, always remember to check that the figure given in the problem is the radius., and not the diameter. If it is the diameter, then the radius is half that.

you half the diamater to get the radius, then you square the radius. Then you times it by 3.14. Always. example. Diameter=4cm then radius =2cm squared=4cm 4x3.14=12.56

Radius squared is half of the diameter multiplied by itself. Example: diameter is 6 inches, radius is 3 inches (half of diameter), radius squared is 9 inches (radius multiplied by itself 3 x 3 = 9).

4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )

Divide the diameter by 2, this will give you the radius. multiply the radius by the radius, this gives you the radius squared. Multiply the raduis squared by Pi (3.14) to get the circumference. Formula : Circumfrence = Pi X R squared so, if the diameter is 10, the radius is 5, the radius squared is 25, 25 X 3.14= circumference

Double the Radius to Calculate the Diameter.

Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.

Area of a circle is pi x radius squared. Diameter is radius times 2. To get radius just divide the diameter by 2. 3.35 divided by 2 is 1.675. Pi x 1.675 squared is approximately 8.81413.

It is: pi*radius squared

Diameter = distance across Radius = half the diameter Circumference = the diameter times pi Area = the radius squared times pi
