The question is in really bad english, but I'm guessing your meant:
'How do I work out the diameter using pi?'
Diameter= Radius2
You don't need to use Pi to work out the diameter.
Unless you have a question that doesn't show you the radius.
Then you do Area divided by Pi which equals the Diameter.

What is the diameter if the circumference is 2.25?
0.7161972439135291... Circumference = pi*diameter which yields circumference/pi = diameter 2.25/pi = diameter 2.25/pi = 0.7161972439135291...
What is the equation to get circumference of a circle if you have diameter?
Circumference = Pi x Diameter (Pi equals 3.14)
What is the formula to find diameter of circle when the circumference is known?
The number pi can be defined as: pi = circumference / diameter. Solving for diameter: diameter = circumference / pi. Pi is approximately 3.14.
How do you find the circumference of a circle knowing only the diameter?
Circumference of a circle: pi times diameter
How is the diameter and circumference on a circle approximate to pi?
the diameter mutliplied by pi is the circumference. From a different view the circumference divided by diameter is pi.
What is the diameter of a circle that is equal to pi?
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
What is the diameter of a 12cm circle?
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
What is the diameter if the circumference is 2.25?
0.7161972439135291... Circumference = pi*diameter which yields circumference/pi = diameter 2.25/pi = diameter 2.25/pi = 0.7161972439135291...
If the Circumference is 12.75 what is the diameter?
Okay, so I am going to be substituting pi for 3.14. The formula for the circumference is 2*pi*r, or pi*diameter. C=pi*diameter 12.75=pi*diameter 12.75/3.14=diameter 4.06050955=diameter
What is the equation to get circumference of a circle if you have diameter?
Circumference = Pi x Diameter (Pi equals 3.14)
What is the formula to find diameter of circle when the circumference is known?
The number pi can be defined as: pi = circumference / diameter. Solving for diameter: diameter = circumference / pi. Pi is approximately 3.14.
How do you find pi using a equation?
If: circumference = pi*diameter Then: pi = circumference/diameter
What is the area of a circle whose diameter is 6 feet?
diameter = 2 Pi R = 6 ft so R=diameter/(2 pi) area = Pi R² = Pi x diameter²/(2² pi²)=6²/(4 pi)
How do you find the circumference of a circle knowing only the diameter?
Circumference of a circle: pi times diameter
What is the Circumference of a circle with a diameter of 7cm?
pi = 21.99/7 pi = circumference/diameter Just multiply your diameter by pi to get a circumference.
What is the diameter of a circle circumference of 47 pi?
The diameter of a circle with acircumference of 47 pi is: 47 (the circumference divided by Pi = diameter).
What is the diameter of a circle if its circumference is 32π?
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32
