sector qs: Charles has a slice of cake; its cross section is a sector of a circle. The radius is r cm and the sector angle is pi/6 radians.
he wants to give half of the slice to Jan. He makes a cut across the sector
show that when they have half the slice, a=r (sqrt pi/6)

Best ResponseYou've already chosen the best response.0if its just the area of the circle, then thats a pretty thin piece of cake...

Best ResponseYou've already chosen the best response.0ok... is that "a" cm on the radius then?

Best ResponseYou've already chosen the best response.0a = r * sqrt(pi/6) eh.... still not clicking anything useful in me head...srry...

Best ResponseYou've already chosen the best response.0if it is exactly half the area of the sector; the the area of the whole is r^2(pi/6)/2

Best ResponseYou've already chosen the best response.0divide that in half and we get (pi r^2)/24 as the area of each piece. area of a triangle can be found by: (side)(side)(sin(t))/2....which in this case is 2side sin(t)/2 = side(sin(t))

Best ResponseYou've already chosen the best response.0a sin(pi/6) = (pi r^2)/24 a (1/2) (24) = pi r^2 12a/pi = r^2 a = pi r^2/12 really
