How many millilitres are tree in three and a quarter litres

There are 3250 milliliters in 3 and a quarter liters. 

Explanation:

There are 1000 milliliters in one liter.

:-1000 *3=3000

1/4 of one liter is 250 milliliters

:-3000+250 is equal to 3250 ml

I hope that helps!:)

< 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
