Question

what is the circumference of a circle with a 4.5 radius?

Answer 1

[AI-generated answer — Bot]

The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14.

Substituting the given radius of 4.5 in the formula, we get:

C = 2π(4.5)

C = 9π

C ≈ 28.27

Therefore, the circumference of a circle with a 4.5 radius is approximately 28.27 units.
