Answer:
hope these would help u....and using the help of these examples you will get the answer!!
r: the radius of the base
h: height
The volume of a cone is given by:
V = π ∙ r2 ∙ h / 3,
where π ∙ r2 is the base area of the cone.
π defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however the value 3.14 is often used.
Example 1: Find the volume of cone, whose radius is 8 cm and height is 5 cm.
Solution:
The formula to find the volume of cone is given by:
V = π ∙ r2 ∙ h / 3
V = π ∙ 82 ∙ 5 / 3
V = 1004.8 / 3 = 334.93 cm3
Thus, the volume of the cone is 334.93 cm3.
Example 2: Find the volume of a cone whose base radius is 2.1 cm and height is 6 cm using π = 22/7
Solution:
The volume of a cone is defined as:
V = π ∙ r2 ∙ h / 3
V = 22/7 ∙ 2.12 ∙ 6 / 3
V = 27.72 cm3
So, the volume of the cone is 27.72 cm3
