How do you find the diameter if you have the area of a circle?
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.
In the formula for the area of a circle what gets multiplied by 3.14?
The radius squared. The radius is half of the diameter
How do you figure out the diameter of a circle?
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.
What is Pi r squared is it the area of a 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.
How do you work out the area of a circle given the diameter?
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
What are the formulas for finding the circumference diameter and radius?
circumference: Pi(3.14) x radius squared Diameter: radius squared radius: diameter divided by 2
How do you find the radius squared?
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).
How do you find the area of a sphere?
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )
Connection between the circumference and the diameter of a circle?
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
How do you calculate radius of the circle when you do not have diameter?
Double the Radius to Calculate the Diameter.
What is the diameter and circumference of circle?
diameter=radius squared circumference=pi times diameter
How do you find the diameter if you have the area of a circle?

What is the area of a 4' diameter circle?
It is: pi*radius squared
What is the area of a circle with a 3.35 in diameter?
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.
What is the basic measurement in a circle?
Diameter = distance across Radius = half the diameter Circumference = the diameter times pi Area = the radius squared times pi
In the formula for the area of a circle what gets multiplied by 3.14?
The radius squared. The radius is half of the diameter
Do you multiply the radius or the diameter of pi?
The raduis.It's pi, r squared. the r stands for radius!
