Solid geometry
1.Diagram 1 shows a solid formed by joining a cone and a cylinder.
4 cm
Diagram 1
The diameter of the cylinder and the diameter of the base of the cone are both 7 cm.
The volume of the solid is 231 cm².By using π = 22 , calculate the height, in cm,
of the cone. 7
Answer:
2.Diagram 2 shows a solid cone with radius 9 cm and height 14 cm. A cylinder
with radius 3 cm and height 7 cm is taken out of the solid.
