Answer:
The volume of solid = π cm³
Step-by-step explanation:
Volume of a cone = 1/3 πr²h
Volume of a hemisphere = 2/3 πr³
Volume of the solid = V(Cone) + V(Hemisphere)
= 1/3πr²h + 2/3πr³
Given that, hieght of cone = radius of cone = radius of hemisphere = 1cm
V(solid) = 1/3 π(1)²(1) + 2/3 π(1)³
= 1/3 π + 2/3 π = 3/3 π = π cm³
