    (b) (i) OAC = OBC = 90 (angle of the tangent) BOA = 360/5 = 72 BCA = 360 - 72 - 90 -90 (sum of angle in quadrilateral) BCA = 108 Reflex BCA = 360 - 108 = 252 (shown) (ii) Total perimeter = 5 * 252/260 * 2 * pi *r...

    (a) (i) 1 line of symmetry (INCLUDING THE SHADE) (ii) (72/360 * pi * R^2) - (pi * r^2)= pi * r^2 1/5 * pi * R^2 = 2 pi * r^2 R^2 = 10 r^2 R^2 is 10 times longer. Hence, ratio = 10:1
