Question

a hemispherical vessel of radius 14 cm is fully filled with sand .this sans is poured on a level ground . the heap of sand forms a cone shape of height 7 cm. calculate the area of ground occupied by the circular base of the heap of sand.​

Answer 1

Answer:

2464 cm sq

Step-by-step explanation:

concept-same volume

v of hemisphere= v of cone

2(pi)r^3/3 = (pi)r^2h/3

2r^3=r^2h

on solving..,we get r=28.

since area is reqd..

ar of circle=(pi)r^2

=22*4*28

ans=2464 cm sq
