The owner of an apartment building wants to install a cylindrical water tank on its side (the base circles on either end) in the basement. the ceiling is 8 feet high, and the space to install in the basement is 8 feet long.

what is the volume, rounded to the nearest cubic foot, of the largest cylindrical water tank that will fit in this space this way?

a. 402 cubic feet
b. 75 cubic feet
c. 691 cubic feet
d. 134 cubic feet

< 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

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
