Question

If the circumference of a circle is 27 mm, then what is the diameter to the nearest tenth of a mm?

Answer 1

To find the diameter of a circle, we can use the formula:

Circumference = π * diameter

Given that the circumference of the circle is 27 mm, we can plug this value into the formula and solve for the diameter:

27 = π * diameter

diameter = 27 / π
diameter ≈ 8.6 mm

Therefore, the diameter of the circle to the nearest tenth of a mm is approximately 8.6 mm.
