Revolution Radius of the cone=6 cm
diameter=12 cm
height=8 cm
slant height²(l²)=h²+r²=64+36=100
l=10 cm
now look at the attached file....
we know the cone is like a triangle...find it's area and perimeter
s= half of perimeter
s=10+10+12/2=16 cm
area= 1/2 bh=1/2*12*8=48 cm²
radius of the sphere= $\frac{area }{s}$
radius= $48/16=3$
volume of the sphere= $\frac{2}{3} \pi r^{3} \\ \\ 
 \frac{2}{3}* \frac{22}{7} *3*3*3 \\ \\ 
=56.57 cm ^{3} 
$
change into liter=0.05657 liter will overflow...
