Question

Given a circle with a circumference of

9π cm, what is the diameter?

a) 3 cm
b) 6 cm
c) 4.5 cm
d) 9 cm

Answer 1

The diameter of the circle is 9 cm.

Step-by-step explanation:

To find the diameter of a circle, we can use the formula: circumference = π * diameter. Given that the circumference of the circle is 9π cm, we can substitute this value into the formula to solve for the diameter.

So, 9π = π * diameter. Dividing both sides of the equation by π, we find that the diameter is 9 cm.
