The textbook emphasizes volumes that are created by rotating regions around lines, but the definition of volume given on p. 431 v = b a(x) dx a also works for determining the volumes of many other types of solids. for each solid below, set up a definite integral that represents the volume of the solid. all of the cross-sections in the figures are perpendicular to the x axis. do not evaluate the integrals.

< 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
