What is the circumference of a circle with a radius of Cm?
The circumference is twice the radius. In other words, if you know the radius, multiply it by 2 to get the circumference.
What formula is used to find the circumference when you know the radius?
Circumference=2*pi*radius
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 determine the circumference of a circle if you know the radius?
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
How do you calculate the diameter of a circle?
If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius
How do know how to make out circumference and diameter if you only know the radius?
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
What is the circumference of a circle with a radius of Cm?
The circumference is twice the radius. In other words, if you know the radius, multiply it by 2 to get the circumference.
What formula is used to find the circumference when you know the radius?
Circumference=2*pi*radius
How do you find the circumference if you know radius?
Circumference of a circle = 2*pi*radius
What is the equation for finding the radius of a sphere when you know the circumference?
The equation for circumference is C=2(pi)(r) where C is the circumference and r is the radius. You can find the radius by plugging in the circumference into this equation and solving the equation.
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)).
What is the formula for finding the circumference of a circle when you only know the radius?
Circumference = 2 x pi x radius
How do you determine the circumference of a circle if you know the radius?
use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
The radius of the circle is 5inches what is the circumference?
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
How do you find the raduis if you know the circumference?
Radius (not raduis) =circumference/(2*pi)
How do you calculate the diameter of a circle?
If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius
How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
