What is the circumference of a circle when the diameter is 3cm?

Answer 1

Well, darling, if the diameter of a circle is 3cm, then the radius is half of that, which is 1.5cm. The circumference of a circle is calculated using the formula C = 2πr, so in this case, the circumference would be 2 x π x 1.5cm, which equals 3π cm or approximately 9.42cm. Hope that clears things up for you, sugar.

Answer 2

The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, if the diameter is 3cm, then the circumference would be C = π(3) = 3π cm, or approximately 9.42477 cm.

Answer 3

circumference = pi x diameter = 3.1416 x 3cm = 9.42cm (approx)
