The equation for circumfrance is 2(pi)r (pi meaning the constant 3.14159, rounded). To find the radius if the circumfrance is known, you would re-arrange this equation to solve for r - it would go from C=2(pi)r into r=C/2(pi).
c = circumference, r = radius.
If the circumference is 2*pi*r, then r = c/(2*pi)=

How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
What is the area of a circle in terms of its circumference?
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
How do you find the area of a circle using circumference?
Circumference = 2*radius Area = 2*pi*radius2 Area = 2*pi*(circumference/2)2
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 show your work to go with how to find the circumference of a circle if the radius is 5?
Circumference = 2*pi*radius In this case radius = 5 units so circumference = 31.4159 units approx.
How do you find circumference using radius'?
Circumference of a circle = 2*pi*radius
How do you find the radius of a cylinder using the circumference and the height?
divide the circumference by pi (3.1416) and divide the product by two that will give you the radius
Sentence using the word radius?
To find the circumference of a circle, you need to multiply the radius by 3.14.
How do you find the radius of a cylinder using the circumference and the width?
If you know the circumference then divide that by (2 x pi) and you will get the radius. The width is unnecessary information.
If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
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 circumference of a circle 2 m radius?
By using the equation 2πr that is used to find the circumference, you get 12.56m
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 formula to calculate circumference using radius?
Circumference = 2*pi*radius
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
How do you find the circumference of a cicle?
To find circumference you must multiply twice the radius by π, or using the diameter, if it gives it to you, multiply that by π.
How do you find radius with only the circumference?
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
