How do you work out the area if given the circumference?

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)


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 a radius if you have the circumference?

You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).


What is the diameter of a 12cm circle?

using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm


What is the equation to get circumference of a circle if you have diameter?

Circumference = Pi x Diameter (Pi equals 3.14)


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 relationship between diamter and circumference?

circumference = pi*diameter or pi = circumference/diameter


The formula for the circumference of a circle is what?

Circumference of a circle = diameter*pi or 2*pi*radius


What is the diameter if the circumference is 2.25?

0.7161972439135291... Circumference = pi*diameter which yields circumference/pi = diameter 2.25/pi = diameter 2.25/pi = 0.7161972439135291...
