Problema Solution
in an experiment,a small spherical drop of oil is allowed to fall onto the surface of water so that it produces a thin film of oil covering a large area
A given that volume of a drop of oil is 12.5mm3, find the number of drops which can bew produced by 5000mm3 of oil
B given that the volume V of a sphere of radius r is 4/3(22/7)r3, express r in terms of V and 22/7
Answer provided by our tutors
In terms or r it is
r=(3*7)/(4*22)
V=4/322/7r3
And in terms of
22/7 it is
=22/7(3*r3)/4
So it is desired answer
