Best ResponseYou've already chosen the best response.1sure. The Radius is 15, so the total circumference of that circle is \[C = 2*\pi*r = 30\pi\]

Best ResponseYou've already chosen the best response.0@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

Best ResponseYou've already chosen the best response.1Angle QCR = 90, so the rest of that is 360  90 =270 Arc QPR goes around 270 of the 360 total circumference, or 3/4

Best ResponseYou've already chosen the best response.1\[QPR = 2*\pi*15 *(\frac{ 270 }{ 360 })\]
