### 28-Mensuration Problem 3

Once again, it is a problem from Student of 10th Standard / 10th grade. I would like to share the method of solving the problem & its presentation with you. Please go through it & make the habit of applying the same technique to solve other problems & please share this technique with your friends & relatives. (Please note one thing that “By distributing our knowledge, it will boost & by keeping it only with us, it will reduce”).

The Problem is very simple. Please see the following Problem.

The Volume of a cone of height 5 cm is 753.6 cubic centimeters. Find the radius of the base of the cone. (π = 3.14) (Note: Don’t use a calculator)

Now we will the Simple method of calculations. Please understand the concepts / steps given in box Brackets [ ].

Given: 1) The volume of a cone = 753.6 Cubic Centimeter
2) The height of a cone = 5 cm.
To find: The radius of the Base of a cone.

Solution:

We Know that the volume of a cone

Therefore

So the radius of the base of a cone is 12 cm.

Like this, you can apply the technique to make use of simple calculations.

I hope, you will definitely implement this technique to save your valuable time of Examination or test. The same logical thinking can be applied to improve your thinking level.

I simply don't want to tell you to go with this simple method of calculation. I want that slowly, you need to mold yourself and improve the thinking level. Only using this technique for solving some problem and getting good scores will not serve my purpose. I want that the entire world needs to improve the thinking skills so that everyone can invent so many beautiful things in the human life.

This is possible only with the help of students like you along with your parents.

Please come ahead and start this beautiful work for yourself and show to the world that we can also build the world with powerful thinking level as everyone is competent.
