A wafer cone is completely filled with ice cream forms a hemispherical scoop, just covering the cone. The radius of the top of the cone, as well as the height of the cone are 7 cm each. Find the volume of the ice cream in it ( in cm3 ).
Required volume= Volume of the ice cream forming the hemisphere + Volume of the ice cream within the cone.
Radius of the hemispherical shape = Radius of the cone =7 cm
Volume of hemisphere =23π(r)3
Volume of a cone =13π(r)3
Required volume =23π(7)3+13π(7)3
=π(7)3=227(7)3
=1078 cm3
