Answer 6

Major arc is 360 - 85 = 275 degrees.

The circumference of a circle is 2*pi*r and the arc is 360 degrees.
That is, 360 degrees corresponds to an arc length of 2*pi*r.
Therefore, 275 degrees corresponds to an arc length of 275 / 360 * 2*pi*r (by proportions). Put r = 13.

Answer 7

The correct answer must also be rounded to two decimal places

Answer 8

When you plug in the numbers into your calculator what do you get?

Answer 9

i got 62.39552076

Answer 10

round it two decimal places.

Answer 11

62.39 or 62.40

Answer 12

Yes, 62.40.

Answer 13

OK!!! THANX @aum

Answer 14

You are welcome.

Answer 15

oh no @aum 62.40 isn't the right answer my program said "Try Again"

Answer 16

That is what I am getting.
The 85 degrees is the minor arc and (360-85 = 275) degrees is the major arc.

Answer 17

Okay, I think I used the calculator pi which is to more decimal places and here they are asking you to use 3.14 for pi. If I do that I get arc length = 62.3638 which when rounded to 2 decimal places gives 62.36. Try 62.36

Answer 18

Ok thank you @aum
