Formula for the volume of a sphere:
V = 4/3 πr^3
V stands for volume
r = radius of the sphere
To clearly understand its application, refer to the example below.
Example:
Determine the volume of a snowball with a diameter of 10 cm.
The shape of a snowball is spherical therefore, we can use the formula for the volume of the sphere.
Since we are given the diameter, we must find for the radius.
d =10 cm
d = 2r
r = d/2
r = 10/2
r = 5
Now we can easily solve the volume of the sphere.
V = 4/3 πr^3
V = 4/3 π(5cm)^3
V = 125/3 cm^3 π
V = 130.9 cm^3
