parts of a circle

Let us learn about parts of a circle.

Radius, Diameter, Chord, Secant line, Tangent line,

To find diameter of circle we need to us this formula = D = 2r or r = (1/2)d

Find the diameter of the circle whose radius is 4 cm.
Solution:
Formula: d = 2r
To find: diameter of the circle.
d = 2*r = 2*4 = 8 cm.

In our next blog we shall learn about formula for sodium carbonate I hope the above explanation was useful.Keep reading and leave your comments.
