How do you find the circumference of a circle using the radius?
Circumference = 2*pi*radius So the radius = circumference/2*pi
What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
What is the formula of circumference?
The circumference of a circle is two times pi times the radius.
How do you find the circumference of a circle when the raduis is a fraction?
The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
What is the formula for the circumference of a circle given a radius?
Circumfrence=diameter X 3.14 (diameter=2 X radius)
How do i work out the circumference of a circle from the radius?
The circumference of a circle with a known radius and can calculated using the following formula: C = 2Π(r)
How do you find the circumference of a circle using the radius?
Circumference = 2*pi*radius So the radius = circumference/2*pi
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 find the circumference if known the radius?
The formula for circumference is pi times diameter. Since a radius is always half the diameter, you just multiply it by 2 and then by pi.
What is the formula to calculate circumference using radius?
Circumference = 2*pi*radius
What is the formula for finding the circumference with radius?
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
How do you get the radius of a circle from the circumfrance?
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
What is the formula that relates circumference and radius?
Circumference = (2) x (pi) x (radius)
What formula is used to find the circumference when you know the radius?
Circumference=2*pi*radius
What is the formula to find circumference when you are given the radius?
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
What is the circumference of a circle that has a radius of 6.74 in?
The circumference of a circle with a radius of 6.74 inches is approximately 42.34 inches. The circumference of a circle is found using the circumference formula: Circumference = 2 * π * radius So, all you have to do is plug in the radius into the formula, and approximate π to be 3.14159.
What is the circumference if the area is 379.94 cm square?
The first step is to work out the radius. The formula for area is pi(r2). That equals 379.94, so plug this into the equation and you get a radius of 10.997. The formula for the circumference is pi(2r). Plug the now known radius in and you get 69.097516968554117299881726353374 Therefore the circumference, if the area is 379.94cm2, will be 69.1cm
