Question

a heap of rice is in the form of a cone if diameter 16m, height is 6m.find it's volume? how much canvas cloth is required to cover the heap.​

Answer 1

Step-by-step explanation:

volume of cone =1/3πrrh

=1/3*22/7*8*8*6

=402.29cm3

Answer 2

Answer:

Step-by-step explanation:

Diameter=16m

Radius = 16/2 = 8m ( radius is the half of the diameter )

Height=6m

Volume of cone =1/3πr^2h

1/3×22/7×8×8×6

=402.28cm^3

Area of the cloth required to cover the heap of rice= Curved surface area of the heap of rice

C.SA area of the conectarte =πrl

But we don't have the slant height or l . So we will take out the l.

L^2=r^2+h^2

L^2=8^2+6^2

L^2=64+36=100m

L=√100

L=10 m

C.SA =πrl

= 22/7×8×10=251.4 m^2

The area of the cloth required to cover the heap of the cloth is 251.4m^2.
