hi. Can you help with this question please?

sure. The Radius is 15, so the total circumference of that circle is \[C = 2*\pi*r = 30\pi\]
anonymous
  • anonymous
ohh
anonymous
  • anonymous
wait so.. what was the formula for this?
DanJS
  • DanJS
Circumference of a circle is 2 times pi times the radius
DanJS
  • DanJS
They want the length of arc QPR which is some fraction of that total circumference

A. S=23.55 B. S=47.10 C. S=70.65 D. S=141.30

Would it be D?

@huaman you said that `i think th formula for this is A= theta/360 *pi*r^2 but im not sure` that formula is for figuring out the AREA of a pie slice like you see below |dw:1441588452712:dw|

Angle QCR = 90, so the rest of that is 360 - 90 =270 Arc QPR goes around 270 of the 360 total circumference, or 3/4
anonymous
  • anonymous
so C?
DanJS
  • DanJS
\[QPR = 2*\pi*15 *(\frac{ 270 }{ 360 })\]
anonymous
  • anonymous
ohh taht makes so much more sense. Thank you very much. I got C.
DanJS
  • DanJS
a fraction (270/360), of the total distance around the circle 2*pi*15
DanJS
  • DanJS
yep yep
