Question

find the number of solid spheres, each of radius 3 cm that could be moulded to form a solid cylinder of height 54 cm and diameter 4 cm

Answer 1

Answer:

the answer is 6

Step-by-step explanation:

first find the volume of a sphere

formula=4phyr^2,where r=3cm(given)

volume of a sphere=36phycm^3..........1

then find the volume of a cylinder

formula=phyr^2h,where h=54cm and r=4/2=2cm

volume of a cylinder =216phycm^3.............2

let the no.of solid sphere be n,then from eq.1and 2

36phy(n)=216phy

n=216/36(phy is cancelled while dividind)

n=6.

therefore, the number of solid spheres is 6.
