Find the angular speed of the tire in radians per minute. Round to the nearest tenth. The tire has a diameter of 42inches and is rotating at a rate of 250rpm. 1804.1rad/min

942.5rad/min

1292.6rad/min

1,570.8rad/min

< 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
