A very interesting topic Diameter of a circle. Do you know how to calculate the area of a circle? Well it is already been explained to you right. I am sure you guys are aware of it. Now lets learn how to calculate the diameter of a circle.
The formula to find the diameter of a circle is as below.
Diameter (d) = 2r.
Lets look at an example below.
Problem No1:-
The circle has the radius 5 meter .find the diameter of the circle.
Observe this problem the radius is already given to you, and we need to find the diameter now.
Radius = 5 meter.
Here, the radius of the circle is given.
Formula to find the diameter = 2r
r = radius
= 2 x 5
=10
The radius of the circle = 10 meters.
Do you have some more examples for circles, look at the globe isn't it a perfect round. Geometry in real life is very important.
