Of a circle
you multiply the radius by two to find the diameter
then you use the formula for circumference which is: diameter times pi
pi is usually used as 3.14 because the real number goes of forever (3.14159265358979323...)
The person who gave us the value of pi you got that answer off a calculator you DO NOT USE A PI BUTTON ON A CALCULATOR because all calculators have a digit limit and you may get a number that is smaller or larger than that number since Pi is indefinate there is no other way that humans can configure pi without using 3.14 or 22/7 just wanted to say that :)

How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
How do you find the radius of a circle with the circumference in terms of pi?
find the radius of a circle with circumference of 42.1
How do you find a circumference of a circle that has a fraction as a radius?
The Circumference of a circle is twice the Radius x Pi (π) OR C = π x 2R ... (2 x Radius) x Pi (π) = Circumference The value of π is taken to be 3.142
What is the circumference when the radius is r?
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
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 the radius of a circle when the circumference is given?
Divide the circumference by the value of Pi, then halve that result.
If the circumference of the circle is 75.36 what is the radius?
To find the radius of a circle when given the circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 75.36, you can plug this value into the formula and solve for the radius. First, divide the circumference by 2π to find the radius. The radius of the circle would be 75.36 / (2 * 3.14159) ≈ 12. The radius of the circle is approximately 12 units.
How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
What is the radius of a circle of a circumference of 121?
To find the radius of a circle with a circumference of 121, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 121, you can plug this value into the formula and solve for the radius. Dividing 121 by 2π will give you the radius of the circle, which is approximately 19.24 units.
How do you find radius with only the circumference?
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
How do you find the area of a circle if you know the circumference?
Circumference = pi x diameter = pi x 2 x Radius (By definition - Step 1) So Radius = (Circumference)/(pi x 2), (find Radius - Step 2) Area = pi x Radius x Radius, (substitute value or radius obtained in step 2)
If the circumference is 37.68 what is the radius?
6 37.68/(2 x pi)
How do you find the radius if you dont know the diameter but you know the cicumference?
Dividing the circumference by 2*pi will give the value of the radius.
How do you find the radius of a circle with the circumference in terms of pi?
find the radius of a circle with circumference of 42.1
How do you find a circumference of a circle that has a fraction as a radius?
The Circumference of a circle is twice the Radius x Pi (π) OR C = π x 2R ... (2 x Radius) x Pi (π) = Circumference The value of π is taken to be 3.142
How do you find the radius if you the the circumference?
Circumference = 2 x Pi x Radius Radius = Circumference / (2 x Pi).
