A ceramic tile has a star-shaped pattern composed of four quartercircles inside a square with side lengths of 3 inches. What is the area of the star? Use 3.14for 77 and round your answer to the nearest tenth.

< 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

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
