Solve for circumference of a circle Worksheet

Mathematically, the circumference of a circle is the product of the diameter of the circle. It is twice the radius and the constant π. It is the length of the complete arc of a circle. The circumference of a circle is also known as the perimeter of the circle. The unit of the circumference is the same as its length, and it is also a linear value.

Teaching Circumference of the Circle Easily 

 

  • Diameter: The distance across the circle through the center. It is denoted by 'd'. 
  • Radius: The distance from the center to any point on the circle. It is denoted by 'R.' 
  •  Π or Pi: It is a constant value, i.e., 22/7 or 3.14.


 

                                        

                                          Circumference of the Circle = 2Πr where 

                                          R = radius of the circle 

                                          Π = 3.14 or 22/7 
 


 

 

 

 

 

 

 

Here is an example of the circumference of the circle. Let’s consider the given example to learn how to solve a question on the circumference of the circle. 


 

Q. If the radius of the circle is 3 cm, find the circumference of the circle. 


 

Step 1: Identify the radius of the circle. 


 

Radius = 3 cm. 


 

Step 2: Use the circumference formula. 


 

Circumference of the circle = 2Πr.


 

2 * 3.14 * 3 = 18.84 cm. 


 

Why Should You Use a Circumference of the Circle for Your Students?


 

  • Solving the area and circumference of a circle worksheet will help your students to get a better understanding of parts of a circle such as radius, diameter, and area. 


 

  • These worksheets will make the students well versed in the concept of a circle being a closed figure having a circumference and not a perimeter.
