Question

Heap of rice is in the form of a cone of diameter 16 and height 6 cm find its volume how much Canvas cloth is required to cover the heap use pi equal to 3.14.​

Answer 1

Answer:

Step-by-step explanation:

well i dont know

Answer 2

The volume of the heap of rice is 401.92 cubic cm

The canvas cloth required is 251.2 sq cm

Step-by-step explanation:

Step 1:

Given,

Height of the cone = 6 cm

Diameter = 16 cm

=> radius = 8 cm

Step 2 :

Volume of the heap of rice  = volume of the cone with above parameters

                                             =   $\frac{1}{3}$  × $\pi$ × r² × h

Where

r represents the cone's radius and h the cone's height

Hence the required volume =  $\frac{1}{3}$  × $\pi$ × 8² × 6 = 401.92 cubic cm

Step 3 :

To find how much canvas cloth is required to cover the rice heap, we need to determine the lateral surface area(LSA) of the cone

LSA =  $\pi$ × r × $\sqrt{r^{2} +h^{2} }$

       =   $\pi$ × 8 × $\sqrt{8^{2} +6^{2} }$    =  =   $\pi$ × 8 × $\sqrt{64 +36 }$  =  $\pi$ × 8 × $\sqrt{100 }$

        =  $\pi$ × 8 × 10 = 251.2 sq cm

Step 4 :

Answer :

The volume of the rice heap is 401.92 cubic cm

The canvas cloth required is 251.2 sq cm
