Answer:
1. Cone Volume = (1/3)πr²h
V = (1/3)(3.14)(3)²(5)
V = (1/3)(3.14)(45)
V = (1/3)(141.3)
V = 47.1 cm³
2. Pyramid Volume = (1/3) LxWxH
V = (1/3) (35x35x11.4)
V = (1/3) (13965)
V = 4655 m³
3. Sphere Volume = (4/3)πr³
V = (4/3) (3.14)(9)³
V = (4/3) (3.14)(729)
V = (4/3) (2,289.06)
V = 3,052.08 mm³
4. Rectangular Prism Volume = LWH
V = 10x4x5
V = 200 cm³
5. Cylinder Volume = πr²h
V = (3.14)(3)²(10)
V = (3.14)(9)(10)
V = (3.14)(90)
V = 282.6 m³
