Volume and Surface Area Of A Sphere| How To Find The Volume and Surface Area Of A Sphere| The Sphere is a very common shape in mathematics but only a few people know the formulas associated with a sphere. This article would guide you on how to check the Volume and surface area of a sphere.

What Is A Sphere?

A Sphere is a shape that looks like a circle but it isn’t a circle and the major difference between a circle and a sphere is that it is a geometrical object in three dimensional space that is the surface of a ball.

How To Find The Volume Of A Sphere

The formula for finding or calculating the volume of a sphere is 4/3πr3 and we would explain the parameters below

π(pi) is a constant 22/7 but some people prefer to use 3.14
r is the radius and it is half of the diameter

How To Find The Surface Area Of A Sphere

The formula for calculating the surface area of a sphere is 4πr2

Questions Involving the Surface Area & Volume Of A Sphere

If the radius of a sphere is 5cm, calculate the Surface area and Volume of the Sphere

SOLUTION
To find the Volume, use the formula 4/3πr3 
Here we set our π as 3.14
V = 4/3*3.14*5*5*5*5
v = 523.33cm3
To find the Surface Area, Use the formula 4πr2
we set our π as 3.14
SA = 4*3.14*5*5
SA = 314cm2
