The circumference of a circle is 6.28 meters. What is the circle's radius? C = 6.28 m

1 answer:

3 0

The circumference of a circle with radius r is c = 2*pi*r. Dividing both sides by 2*pi gives r = c/(2*pi). For c=6.28 the radius is r= 6.28/(2*pi) which is approximately 1 since pi is approximately 3.14
