Question

The radius of a circle is 1 foot. What is the circle's circumference?

r=1 ft
Use 3. 14 for ​

Answer 1

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

In this case, the radius is 1 foot, so:

C = 2πr

C = 2(3.14)(1)

C = 6.28

Therefore, the circumference of the circle is approximately 6.28 feet.
