Question

Help finding the circumference

Answer 1

approximately equal to 72 centimeters

Step-by-step explanation:

The formula for the circumference of a circle is 2
`\pi`r.

The formula for finding the radius with an arc and an arc length is 180 times l over
`\pi` times the angle.

`(3420)/(298.45)` which is approximately equal to 11.46

11.46 is our radius so the circumference is 2
`\pi`(11.46) or about 72
