Question

Find the circumference of the circle use 3.14 r=2

Answer 1

Explanation:

11

Answer 2

Answer: 12.56 units

Work Shown:

`C = \text{circumference} = \text{perimeter of the circle}\\\\C = 2*\pi*r\\\\C \approx 2*3.14*2\\\\C \approx 12.56\\\\`

Note: If you were given the diameter, then divide by 2 to find the radius, so you can use it in the formula above. Or you could use this formula
`C = \pi*d`
