Given :
The diameter of the circle is 8 cm
To find:
The radius of the circle
So,
We know that
The diameter of a circle is two times it's radius
OR
The radius is half of the diameter.
Therefore,
Diameter = 2 × Radius
OR
Radius = ½ of diameter
So,
Radius of the circle
= diameter ÷ 2
= 8 ÷ 2
= 4 cm
Hence,
The radius of the circle is 4 cm
- The formula to find the circumference of a circle = 2πr units.
- The formula to find the area of a circle = πr² unit sq.
