help please :) fan and medal

sammixboo (sammixboo):

Do you know the Pythagorean theorem?

OpenStudy (song_of_the_sole):

a^2+b^2=c^2

sammixboo (sammixboo):

Right! That is going to be used for solving this problem

sammixboo (sammixboo):

Since we know the radius is 28 and OC = 9, let's draw it on our figure first |dw:1464744762658:dw|

sammixboo (sammixboo):

We are going to solve for CB, then multiply it by 2 to get AB. DO you have an idea of what to do next?

sammixboo (sammixboo):

Correct. We have to solve for B

sammixboo (sammixboo):

9^2 + b^2 = 28^2

sammixboo (sammixboo):

That's right. Do you know what to do next?

sammixboo (sammixboo):

Approximately, yes, so let's put that on our figure |dw:1464745076551:dw|

sammixboo (sammixboo):

No, we are trying to find AB, but CB is 26.5

sammixboo (sammixboo):

AB is double CB, so what is 26.5*2?

sammixboo (sammixboo):

And that's your answer. Seems like you got the hang of this ;)
