find the circumfrence of a circle with r=7

1 answer

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. Given that the radius (r) is 7, we can substitute this value into the formula:

C = 2π(7)
C = 14π

Therefore, the circumference of a circle with radius 7 is 14π, or approximately 43.982.
