Answer:
1. Â volume of cone = 288Ï€ cube units
2. Â volume of cylinder = 972Ï€ cube units
3. Â volume of sphere = 288Ï€ cube units
4. Â volume of cylinder = 288Ï€ cube units
5. Â volume of sphere = 972Ï€ cube units
6. Â volume of cone = 972Ï€ cube units
Step-by-step explanation:
1. Â Radius of cone (r) = 12units
height of cone(h) Â = 6units
volume of cone = Ï€/3r²h Â
=Ï€/3.12.12.6
=Ï€.12.12.2
=288Ï€ cube units
2. Â diameter of cylinder(d) = 12units
radius of cylinder (r) = 6units
height of cylinder (h) = 27 units
volume of cylinder = πr²h
= π.6.6.27
= 972Ï€ cube units
3. Â diameter of sphere = 12 units
radius of sphere = 6 units
volume of sphere = 4π/3.r³
= 4Ï€.2.6.6
= 288Ï€ cube units
4. Â diameter of cylinder (d) = 8 units
radius of cylinder (r) = 4 units
height of cylinder(h) = 18units
volume of cylinder = πr²h
= π.4.4.18
= 288Ï€ cube units
5. Â radius of sphere(r) = 9 units
volume of sphere = 4π/3.r³
= 4Ï€/3.9.9.9
= 4Ï€.3.9.9
= 972Ï€ cube units
6. Â diameter of cone (d) = 18 units
radius of cone (r) = 9 units
height of cone (h) = 36 units
volume of cone = π/3.r².h
= π/3.9.9.36
= π.3.9.36
=972Ï€ cube units
