The point (2, 0) lies on a circle with the center at the origin. what is the area of the circle to the nearest hundredth? use 3.14 for ?

pi, p = 3.14

radius, r = 2

area, a = pr^2

a = 3.14 x 4 = 12.56

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
