The cylindrical drinking glass is holding 150 cubic centimeters of water. what percent of the total volume of the glass is filled with liquid? 6cm radius and 12cm height

First find radius.

Given diameter=6, so radius =3.

Now volume of cylinder = pi * r^2 * h

So volume is 3.14*9*12 = 339.12

Now its given to find the percent. So just do 150/volume.

150/339.12=44%

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
