Circumference = 2piR --> 2 x 3.14 x 4 = 25.12 centimeters
A circle with a radius of 2.8 centimeters has a circumference of 17.59 centimeters.
Circumference = 2*pi*radius So Radius = Circumference/(2*pi) = 8/(2*pi) = 4/pi = 1.2732 (to 4 dp)
A circle with a radius of 15.5 centimeters has a circumference of 97.39 centimeters.
A circle that is 25.13272 cm in circumference.
The radius is 7cm
The wheel's circumference is: 219.9 centimeters.
2 times 4 times pi (3.14)
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
If the circumference of a circle is 132cm its radius is: 21.01 cm
A circle with a radius of 4.5 centimetres has a circumference of 28.27 centimetres.
The radius is: 4.802 cm
