Question

A cylindrical bucket 32cm high
and base radius 18cm is filled with sand completely. This bucket is emptied on the ground and a conical heap of sand is formed. If the height of the conical heap is 24cm , find the radius and slant height of the heap​

Answer 1

h=32cm r=18cm h=24cm. volume of cylinder=volume of cone √π2h=1/3√π2h. π2=3√π2h/√4. 3π2h/π. π=36. l = π2 +h2 =√30power2. + 24power2 √576+1296=✓1872 answer is 36√13cm
