It depends on the information you have. If you remember the formulas for area and circumference, you can plug in what information you know in order to solve for the information you don't.
You can multiply the radius by 2.
If you are given the area, divide by pi (3.14) and then take the square root and multiply by 2.
If you are given the circumference, divide by pi (3.14).
The DIAMETER of a circle is any point on the circle to another point, straight across.
The RADIUS of a circle is like the diameter, only from any point, to the very middle.
To find AREA: multiply circumference by pi.
To find Diameter, multiply the radius by two.
to find radius: divide diameter by 2.

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
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How can i find circumference if you know diameter?
Circumference = Pi * diameter
What is the circumference of a circle 7 feet using 3.14 for pi?
The circumference of a 7-foot diameter circle using 3.14 for Pi is: 21.98 feet (diameter x Pi = circumference).
What is the importance of pi?
the importance of pi is when u do have the diameter of a circle and u have the radius you can find the diameter of the circle and the circumference
How do you find pi using a equation?
If: circumference = pi*diameter Then: pi = circumference/diameter
How do you find the diameter of a circle using pi?
Diameter = circle's circumference/pi
How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
How do you Find the circumference of a circle using pi?
pi times diameter
How do you find diameter of circle using the circumference?
Diameter = circumference/pi
How do you find the circumference of a circle using only the diameter?
Pi x diameter
How do you find the circumference of a circle using the diameter?
multiply the diameter times pi (3.14159265)
How do you find the circumference of a circle using the length of the diameter?
Multiply the diameter by the constant pi.
How do you find the diameter when given the circumference?
Since circumference is found by multiplying pi by the diameter of the circle, the diameter can by found using the inverse operation. diameter = circumference/pi
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Can you find the circumference of a circle by using radius and diameter?
circ = 2 pi r = pi d
How do you work out diameter from using circumference?
EDIT: To find the diameter, using the circumference - you divide the circumference by the value of Pi - Snakester1962 (Supervisor)
