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 = r

What is the circumference of a circle when the radius is 3 inches?
The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)
What is the circumference of a circle with a 3-inch radius?
A circle with a radius of 3 inches has a circumference of 18.8 inches
If a circle has a deameter of 6 inches about how long is its circumference?
Diameter = 6 inches Radius = 3 inches Circumference = 2 x pi x radius = 18.84955592 inches
What is the circumference of circle with radius of 3 inches and diameter of 10 in ches?
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.
What is the circumference of a circle when the radius is 3 inches?
The circumference of a circle when the radius is 3 inches is: 18.8 inches (r x 2 x Pi = circumference)
What is the circumference of a circle with a 3-inch radius?
A circle with a radius of 3 inches has a circumference of 18.8 inches
What is the radius of a circle with a 21 inch circumference?
the radius is 10.5 inches. * * * * * Wrong! Circumference = 2*pi*Radius Or, Radius = Circumference/(2*pi) So circumference = 21 inches implies radius = 3.34 inches (to 3 sf)
What is the circumference if the radius is 3 inches?
C = 18.8 inches
If a circle has a deameter of 6 inches about how long is its circumference?
