Answer:
21.98 units
Step-by-step explanation:
The circumference of a circle can be found using:
c=2πr
We know that the radius is 3.5, and we know we are rounding pi to 3.14 We can substitute 3.5 for r and 3.14 for pi.
c=2*3.14*3.5
Multiply all the numbers together
c=6.28*3.5
c=21.98
The circumference of the circle is 21.98 units.
