The rubber track for a toy digger goes around four circular wheels of diameter 8 cm, as shown.

(b) Calculate the length of the rubber track that goes around the four wheels.

Give your answer correct to one decimal place.

< 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
