A circle with a radius of 4.5 cm has a circumference of 28.27 cm
Doubling the radius doubles the circumference.
18 pi
Circumference of the circle: 2*pi*9 = 18*pi cm
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a radius of 9 cm, the circumference would be ( C = 2\pi \times 9 ) cm, which simplifies to ( C = 18\pi ) cm. Approximating ( \pi ) as 3.14, the circumference is approximately 56.52 cm.
