Work it out the circumfrance of a circle is pie x the diameter!
The circumference of a circle is (pi) x (diameter), or (2 pi) x (radius).
it uses to find out thearea and circumference of circle. diameter=2*radius
Twice the radius times pi or the diameter times pi
Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
The circumference of a circle with a known radius and can calculated using the following formula: C = 2Π(r)
c=2*pie*r c= circumference r= radius.
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Circumference = 2*pi*radius In this case radius = 5 units so circumference = 31.4159 units approx.

C=2*pi*r Radius is the circumference of the circle divided by 2pi. Therefore, if the circumference was C then the following formula works out the radius: r=C/(2*pi)

12.99 to two decimal places. I'll leave you to work out how the answer is obtained !
Circumference of a circle is pi * diameter. Diameter is 2 * radius. So if you know the radius, circumference is 2 * pi * radius. Now choose an appropriate approximation for pi (3.14, or 3.1416, or even the fraction 22/7), depending on your application. This will work for ANY circle, no matter how big or small it is, as long as it's a true circle and not a different elliptical shape, e.g. an oval.
