How do you find the radius of a circle if you have the circumference?
Easy to do. First, divide the circumference by Pi (about 3.1416). The result is the diameter. Now, divide the diameter by two to get the radius.
How do you find diameter and circumference?
Where C=circumference, r= radius and d=diameter To find circumference: C=2 x pi x r or you can use the formula C=pi x d To find diameter just multiply the radius by 2 if you know what the radius is. If you do not know the radius, but you know the circumference and need diameter use the following formula: C/pi=d Happy Computing!!!
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
How do you find circumfrence?
The process you would use to find the circumference of a circle completely depends on what information you already have about the circle. For example, you might be given the circle's area, or its radius, or its diameter, or the length of one radian of arc along the circumference, and each of those would require a different method to find the circumference. The easiest example is the one where you know the circle's diameter. In that case, simply multiply the diameter by (pi) to get the circumference. The next easiest case is the one where you have the circle's radius ... let's say the radius is 1.5 meters. Knowing that the radius is half of the diameter, you first double the radius, and find that the diameter 3.0 meters. Then you get the circumference just as you did in the first example ... multiply the diameter by (pi). With a radius of 1.5 meter, you would find that the circumference is about 9.425 meters. (rounded)
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How do you find the circumference of an object if you only have the diameter and the radius?
2 x pi x radius
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 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.
How do you find the radius and diameter when they give you a circumference?
divide the circumference by pi ( 3.146) which will give you the diameter divide that by 2 and you have the radius
What formula do you use to find the radius diameter and circumference of a circle?
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
