In this quiz, an attempt is made to give the child a familiarity and practice on how to find the volumes of the given shapes and in particular, it is coned here. In a layman definition volume is the product of base area and the height. For the cone, it is quite different and hence it is better to rely on the conventional formulas. The child has to find out the volume of the cones that are displayed and each of them have their dimensions such as radius and height. The child will get sufficient practice while solving the problems in this quiz.

What is a cone and how to find its volume?

A cone is a three-dimensional shape with a circular base and a pointed top. The height of a cone is the straight line from the center of the circular base to the pointed top. To find the volume of a cone, you need to know the radius of the circular base and the height of the cone.

The formula for finding the volume of a cone is:

Volume = (1/3) x π x radius^2 x height

The symbol “π” (pronounced “pi”) is a special number that is approximately equal to 3.14. It is used in many math formulas, including the formula for finding the volume of a cone.

To find the volume of a cone, you start by measuring the radius of the circular base. Let’s say the radius of the cone is 5 cm. Next, you need to measure the height of the cone. Let’s say the height of the cone is 8 cm. Now you can use the formula to find the volume of the cone. Plugging in the values for the radius and the height, we get:

Volume = (1/3) x π x 5 cm^2 x 8 cm = (1/3) x 3.14 x 5 cm^2 x 8 cm = 20.94 cm^3

This means the volume of the cone is 20.94 cubic centimeters.

Here’s another example:

Imagine you have a cone with a radius of 6 cm and a height of 10 cm. To find the volume of this cone, you would use the formula:

Volume = (1/3) x π x 6 cm^2 x 10 cm = (1/3) x 3.14 x 6 cm^2 x 10 cm = 31.44 cm^3

So the volume of this cone is 31.44 cubic centimeters.

It’s important to remember that the radius of a cone is always a straight line from the center of the circular base to the edge. So if you wanted to, you could use a different straight line as the radius and the volume of the cone would be different.
