Answer 2

Step-by-step explanation:

Given A heap of rice is in the form of a cone of diameter 16 m and height 6 m. find its volume? how much canvas cloth is required to cover the heap(use pie = 3.14)

• Given diameter of cone = 16 m and height = 6 m
• So radius r = d/2 = 16 / 2 = 8 m
• Now surface of cone = πrl
• Also volume of cone = 1/3 πr^2 h
• Slant height = √r^2 + h^2
• So l = √8^2 + 6^2
• So l = √64 + 36
• So l = √100
• Or l = 10
• Volume of heap = 1/3 πr^2h
•                           = 1/3 x 3.14 x 8^2 x 6
•                          = 401.92 m^3
• Surface area of cone = 3.14 x 8 x 10
•                                 = 251.2 m^2

Therefore canvas cloth required to cover the heap will be 251.2 m^2
