56.549 cm
Doubling the radius doubles the circumference.
Circumference of the circle: 2*pi*9 = 18*pi cm
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
If a circle circumference is 30 the radius is: 4.77
The radius of a circle with a circumference of 59 is: 9.39
Doubling the radius doubles the circumference.
56.549 cm
Circumference of the circle: 2*pi*9 = 18*pi cm
The equation for circumference is C = 2*pi*r, where r is the radius of the circle and pi is a constant = 3.14159... Assuming that you mean a 9cm radius, the circumference is therefore: C = 2*pi*r = 2*pi*9cm = 18cm*pi = ~56.549cm
The circumference of a circle that is 9 cm wide is: 28.274 cm
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
