yellow circle = 43.96 ft

purple circle = 28.26 ft

Step-by-step explanation:

yellow circle = πd = (3.14)(14) = 43.96 ft

purple circle = πd = (3.14)(9) = 28.26 ft

you need more information to answer this question

step-by-step explanation:

< 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
