– π (pi) is a mathematical constant, approximately equal to 3.14159 If we know the circumference of a circle, we can easily find out its radius by rearranging this formula and solving for ‘r’: r = C / ...

The circumference of a circle is the distance around the shape. The ability to round a number to a number of decimal places or to a number of significant figures means that answers can be written to ...

In geometry, the circle is a fundamental shape that holds immense importance. Central to a circle’s properties is its radius – the distance from its center to any point on the circumference. Knowing ...

The chapter on “Circles” forms an important part of Mathematics. This chapter includes many interesting and useful formulae. One such formula is the circumference of the circle. Students must know and ...

When working with circles it is important to recognise and be able to name different parts of the circle. A segment of a circle is an area enclosed by a chord and an arc. What is the name given to a ...

This is a simple Python program that calculates the Area and Circumference of a circle by accepting the radius as input from the user.

Enter radius: 6 Circumference: 37.7 Area: 113.1 Continue? (y/n): n Goodbye. You created 2 Circle object(s). Operation: The application prompts the user to enter the ...

The radius of a circle or a sphere is the distance between the center and the edge. The radius can be used to calculate a circle's diameter, area and circumference. Likewise, a sphere's volume is ...
