the formula for the circumference is
c=2(pi)r
Since you already have the circumference, just plug it into the formula, and solve:
3=2(pi)r divide by 2pi
0.47746483 = rChat with our AI personalities
The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)
A circle with a radius of 3 inches has a circumference of 18.8 inches
Diameter = 6 inches Radius = 3 inches Circumference = 2 x pi x radius = 18.84955592 inches
A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.
The radius of a circle with a circumference 36 inches is: 5.73 inches.
