#A Cylindrical container of radius 6cm and height 15cm is filled with ice cream. The whole ice cream has to be distributed to 10 children in equal cones with hemispherical tops. If the height
of the conical portion is 4 times the radius of its base , find the radius of the cream cones.<br>
of the conical portion is 4 times the radius of its base , find the radius of the cream cones.<br>
# To imagine a cone , Hemisphere,and cylinder
# To imagine a cone , Hemisphere,and cylinder
# To imagine a cone having Hemispherical top
# To imagine a cone having Hemispherical top
r=3cm<br>
r=3cm<br>
Hence the radius of cream cones=3cm
Hence the radius of cream cones=3cm
