you do this:rxrx3.14 in words radius times radius times 3.14 first times the radius by itself then multiply

The formula given in the above answer is for the area of a circle, not its circumference!
Circumference = 2*pi*r or pi*d where r is the radius, d = 2*r is the diameter
and pi is the irrational number which is approximately equal to 3.14159.

How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
How do you find the radius of a circle is you have the circumference?
pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
How to find the radius of a circle with the circumference?
Divide circumference by pi, that gives diameter. Radius is half of diameter
How do you find the length of of the radius of a circle?
You can either measure it, or calculate it if you know the diameter (radius = diameter / 2), or the circumference (radius = circumference / (2pi)).
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
How do you find the radius of a circle is you have the circumference?
pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
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
How to find the radius of a circle with the circumference?
Divide circumference by pi, that gives diameter. Radius is half of diameter
How do you find the circumference of a cicle?
To find circumference you must multiply twice the radius by π, or using the diameter, if it gives it to you, multiply that by π.
How do you find the circumference if you know the radius?
Okay finding circumference from knowing the radius right? The radius is equal to half the diameter and circumference is equal to pi * diameter. So double the radius and multiply it by 3.14 then you will get the circumference!
How do you find the length of of the radius of a circle?
You can either measure it, or calculate it if you know the diameter (radius = diameter / 2), or the circumference (radius = circumference / (2pi)).
How do you find length and width given the circumference?
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
How do you find out the circumference from the diameter?
circumference of a circle = pi*diameter or 2*pi*radius
How do you find the diameter and circumference of a circle if the radius is 7?
Diameter = Radius*2 = 14 units. Circumference = pi*Diameter = 43.98 units.
