Question

find. volume. of. rice. and. how much. canvas

Answer 1

we have, r = 24/2 = 12m
and h = 3.5m
l = √(h^2 + r^2)
= √[(3.5)^2 + (12)^2]
= √(12.25 + 144)
= √156.25 = 12.5m

Volume = πr^2h/3
= (22×12×12×3.5)/7
= 1584 m^3

area if canvas required = CSA of cone
= πrl
= (22×12×12.5)/7
= 471.42 m^2

Answer 2

hi
its diameter is 24m
so, its radius will be 12m
volume of the rice=πr^2*h/3
                            =22/7*12*12*3.5/3
                            =528cubic meters
                              
       WKT,
l^2=r^2+h^2
     =12^2+3.5^2
     = 144+12.25
     =166.25

cloth required to cover the heap=TSA of cone
                                                   =πr(r+l)   
                                                   =22/7*12(12+166.25)
                                                   =6722.57142857
