You're supposed to know that
Circumference = (pi) x (diameter)
Divide each side of this equation by (pi) :
Diameter = Circumference/pi
And you also know that Diameter = 2 x Radius .
2 x Radius = Circumference/pi
Divide each side of that one by 2 :
Radius = Circumference/2 x pi .
and that's exactly what you need.
What else can I help you with?
If the circumference of the circle is 75.36 what is the radius?
Well, isn't that a happy little question! To find the radius of a circle when you know the circumference, you can use the formula: radius = circumference / (2 * π). So, if the circumference is 75.36, you can plug that into the formula and find the radius. Just remember, there are no mistakes, just happy little accidents in math!
What is the radius of a circle whose circumference is 94.2?
Well, isn't that a happy little question! To find the radius of a circle when you know the circumference, you can use the formula: circumference = 2 * pi * radius. So, if the circumference is 94.2, you can plug that in and solve for the radius. Just remember to divide by 2 * pi to find the radius, and you'll have your answer in no time!
What is the formula for finding the diameter of a circle when the circumference is given?
the Circumference is pi times 2 times radius If you know circumference then you can find the radius. once you know the radius just multiply by 2 to find the diameter.
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 ----
Given the circumference of a circle what is the radius?
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*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 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)
When given radius how do you find the circumference?
Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)
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
How can I find circumference when only area is given?
Radius = square root of (area/pi) Circumference = 2*pi*radius
When given the circumference how do you find the diameter and radius?
divide 3.14 by circumference and d=2r
How do you find the radius of a circle when only given the circumference?
Divide the circumference by (2*pi)
How do you find radius of a circle if circumference is given?
circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) Divide the circumference by two times π (≈ 6.283).
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
How do you find circumference given radius?
2 pi rthis is the equation of the circumference of a circle. just multiply out 2 times pi(3.14159) times the radius that you were given.
How do you find circumference of a circle given?
circumference of a circle = 2*pi*radius or pi*diameter
