Answer:
:
= 4 : 1
Explanation:
Given that:
Volume of a cylinder = h
For cylinder A, =
=
and
= 4
.
Volume of cylinder A = ×
= 4
Volume of cylinder B =
=
To determine the ratio of their masses, density (ρ) is defined as the ratio of the mass (M) of a substance to its volume (V).
i.e ρ =
Thus, since the cylinders are made from the same material, they have the same density (ρ). So that;
density of A = density of B
density of A =
density of B =
⇒ =
The ratio of mass of cylinder A to that of B is given as;
=
⇒ =
Therefore, :
= 4 : 1
