Answer 1

how many degrees are in a full circle?

Answer 2

360

Answer 3

so, if im in the center of the circle, and i turn all the way around, how many degrees have a turned?

Answer 4

this relates your angle to the arc degrees ....

Answer 5

... 28, but still the same concept

Answer 6

so then its B?

Answer 7

of course not ...

Answer 8

im confuzzled

Answer 9

if you are at the center of the circle (the arc degree of a circle is 360) ; and you turn all the way around so that you are facing the same direction you started in ... how many degrees have you turned?

Answer 10

360

Answer 11

so, if the arc degree is 360, and the angle of rotation is 360 ... how does this relate to your stated problem of:

arc degree is 28, angle of rotation is ____

Answer 12

A! Equal!

Answer 13

correct :)
