Question

A solid toy is in the form of a hemisphere surmounted by a right circular cone the height of the cone is 4cm and the diameter of the abse is 8cm​

Answer 1

Answer:

200.96cm³

Step-by-step explanation:

volume of cone

V=1/3πr²h

V=1/3π4²×4

V=64/3π

volume of hemisphere

V'=2/3πr³

V'=2/3π4³

V'=128/3π

V(total)=V+V'

V(total)=64/3π+128/3π

V(total)=192/3π

V(total)=200.96cm³
