Question

Diameter of a circle is 6 miles, what is the circumference

Answer 1

C≈18.85mi

Explanation:

E.G : to solve the equation for the diameter of the circle, d= C/π. In this example, "d = 12 / 3.14." or "The diameter is equal to twelve divided by 3.14." Divide the circumference by pi to get the answer. In this case, the diameter would be 3.82 inches.

Answer 2

circumference formula for circle: 2πr

diameter/2=radius, so the radius for this problem is 3 miles

C=2πr

=2(3)π

=6π
