a circle has a radius of 4 cm wha is its circumstance

1 answer

The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius

Given that the radius is 4 cm, we can substitute this value into the formula:
Circumference = 2 * π * 4
Circumference = 8π cm

Approximating the value of π to 3.14, the circumference of the circle is:
Circumference ≈ 8 * 3.14
Circumference ≈ 25.12 cm

Therefore, the circumference of a circle with a radius of 4 cm is approximately 25.12 cm.
