Radius of Sphere = Circumference of Sphere÷2𝜋
Let's take an example to understand-
Q- Find the radius of a sphere if its circumference is 22m long.
Solve:
Circumference = 22m
Radius of Sphere = Circumference of Sphere÷2𝜋
= 22÷2𝜋
= 11÷𝜋
= 11÷3.14
= 3.50 (approx)
The radius of a sphere=3.50m (approx).
