Question: If a circle C with radius 1 rolls along the outside of the circle x 2 + y 2 = 4 9 , a fixed

If a circle C with radius 1 rolls along the outside of the circle x2+y2=49, a fixed-point P on C traces out a curve called an epicycloid, with parametric equations x=8cos(t)-cos(8t) and y=8sin(t)-sin(8t). Note: Here, 0t2. Use one of the formulas A=oCxdy=-oCydx=12oCxdy-ydx, to find the area it encloses.
