Circumference=Diameter * Pi
Diameter= Radius *2
Radius=(Circumference/Pi)/2
54/Pi=17.18873385
17.18873385/2=8.594366927
A circle with a radius of 15.5 centimeters has a circumference of 97.39 centimeters.
radius = 54/(2*pi)
The radius is 7cm
A circle with a radius of 4.5 centimetres has a circumference of 28.27 centimetres.
The radius is: 4.802 cm
54 cm
A circle with a radius of 2.8 centimeters has a circumference of 17.59 centimeters.
A circle with a radius of 15.5 centimeters has a circumference of 97.39 centimeters.
radius = 54/(2*pi)
The radius is 7cm
Well, darling, if the circumference is 54, then we can use the formula C = 2πr to find the radius. Just plug in the circumference (54) and solve for r. So, 54 = 2πr, divide by 2π, and you'll find that the radius is 27/π or approximately 8.59. Voilà!
The wheel's circumference is: 219.9 centimeters.
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
50.24
A circle with a radius of 4.5 centimetres has a circumference of 28.27 centimetres.
The radius is: 4.802 cm
circumference = 2*pi*9
