Every shape has a parameter called as perimeter which is defined as the sum of all the sides. Since a circle is not composed of straight lines, it becomes a different picture to calculate the perimeter. Here, the perimeter is no more the same term, rather circumference is an appropriate word to define it. To find out the circumference of the circle it is important to first find the radius of it. Here in this quiz, the questions give a good practice on working out this pattern and the child will be pleased to solve the questions because of the pictures displayed in it.

How to find circumference of a circle?

The circumference of a circle is the distance around the outside of the circle. To find the circumference of a circle, we use a special formula that involves the radius of the circle. The radius is the distance from the center of the circle to the edge.

The formula for finding the circumference of a circle is: circumference = 2 x pi x radius

The symbol for pi is a special number that is a little bit more than 3.14. It is represented by the Greek letter “π”. Pi is a constant, which means it always has the same value, no matter what size the circle is.

So, let’s say we have a circle with a radius of 4 inches. We can use the formula to find the circumference like this: circumference = 2 x 3.14 x 4 = 25.12 inches

It’s important to remember that the circumference is always measured in a straight line, around the outside of the circle. It’s not measured along the curved part of the circle.

Now let’s try an example. Imagine we have a circle with a radius of 6 inches. What is the circumference of this circle? To find the answer, we can use the formula like this: circumference = 2 x 3.14 x 6 = 37.68 inches.

So, to find the circumference of a circle, we use the formula: circumference = 2 x pi x radius. We just need to plug in the value for the radius, and then we can calculate the circumference. It’s a good idea to use a calculator to do the math, because it can be a little tricky.
