Formula: Circumference=pi x diameter. As the diameter is always 2 x the radius, we get
C = 2 * pi * radius = 47.124.

What is the radius of a pencil?
You can use the circumference of the pencil and the circumference formula to find the radius. Set the measured circumference equal to 2pi*radius and solve. I measured it to about .75 of an inch, so: .75=2pi*radius r=.75/2pi
If the radius of a cricle is increased by 75 percent then its circumference will be increased by?
The cricle's circumference is a linear function of its radius, so they change in direct proportion.If the radius increases by 75%, the circumference also increases by 75%.
How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
What is radius of a circle with circumference of 75 in?
11.93662073 inches
How do you find radius with only the circumference?
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
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 the radius if you the the circumference?
Circumference = 2 x Pi x Radius Radius = Circumference / (2 x Pi).
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 do you find circumference using radius'?
Circumference of a circle = 2*pi*radius
When given radius how do you find the circumference?
Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)
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 when you have the circuference?
circumference = pi * 2radius (diameter) so to find radius you use circumference/(2 x pi) this will find radius ----
