Question

Help with Circumference of a circle?? WIll give Medals,help!!

Answer 1

@superdav815 Please help me if you can.

Answer 2

\[AB = r(\theta)\]

Answer 3

= (21/pi)(2*pi/3)

Answer 4

circfumference implies the length of the perimeter of the full circle for 360 degrees. this is 120 degrees, so 1/3 of the perimeter. which is 42/3 = 14

Answer 5

=42/3

Answer 6

since we know there is a linear relationship between circumference and arc length we can also look at it as:

length perimiter/360 degrees = length AB/120 degrees

Answer 7

Thank you both.
