Find the circumstances of the circle the radius of the circle is 3.5 use 3.14 for pi

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.
