To answer this question we need to add 39.95+1.95=41.9
Then just subtract: 90.75-41.9=48.85
The answer is 48.85.

Namely, how much is 18.3% from 188? well if we take 188 to be 100%, then
The volume of the cylinder having diameter 12 cm and height of 4 cm is 452
.
Given diameter of cylinder be 12 cm and height of cylinder be 4cm.
We are required to find the volume of cylinder.
Volume is the quantity of substance a container can hold in its capacity.
Diameter=12 cm
Radius=6 cm (Radius is always equal to half of diameter)
Volume of cylinder=π
We have to just put the values of r, h and π in the formula to get the volume of the cylinder.
Volume=π
=3.14*4*36
=452.57 
After rounding off we will get 452
.
Hence the volume of cylinder is 452
.

Question is incomplete as it should include height of cylinder be 4cm.
Equation for density is mass/volume
Mass=22.62 g
Volume= 22/7 x 1/2^2 x 4
3.14 x 0.5 x 0.5 x 4
=3.14 cm3
Mass/ Volume
22.62/3.14
7.2 g/cm3 is the answer
