Answer:
The volume of the cone is 301.44 meter cube.
188.4 square meter cloth is required to cover the heap.
Step-by-step explanation:
Given : A heap of rice is in the form of a cone of diameter 12 m and height 8m.
To find : Its volume how much Canvas cloth is required to cover the heap.
Solution :
The diameter is 12 m
Radius is 6 m
Height is 8 m
Volume of the cone,
V=\frac{1}{3}(3.14) (6^2) (8)
V=\frac{1}{3}(3.14) (36) (8)
V=301.44m^3
So, The volume of the cone is 301.44 meter cube.
For the canvas we have to find the curved surface area of the cone,
CSA=\pi rl
Where, l is the slant height
l=\sqrt{h^2+r^2}
l=\sqrt{8^2+6^2}
l=\sqrt{64+36}
l=\sqrt{100}
l=10
Substitute the values in the formula,
CSA=(3.14)(6)(10)
CSA=188.4m^2
Therefore, 188.4 square meter cloth is required to cover the heap.
