use 3.14 for pi for your answer
r=1
Answer: 6.28 units
Step-by-step explanation:
The circumference of a circle can be found with the formula C = 2πr where r is the radius. Here, we are given the radius and a different value for π (pi).
Given:
C = 2πr
Substitute given values:
C = 2(3.14)(1)
Multiply:
C = 6.28 units
The circumference of the given circle is 6.28 units.
