Asports fan is designing a foam cushion to use on
stadium bleachers. the foam is 10 cm thick, and can
be cut to any length and width to form a rectangular
prism. he wants to make a fabric covering for a piece that has a volume of 5000 cm3. to the nearest tenth of a centimeter, what dimensions should he choose to use the least amount of fabric covering?

Three into five thousand

Three into five thousand

< 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
