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
