### Transcript

• 1. ppr maths nbk 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. Diagram 2 Calculate the volume,in cm³,of the remaining solid. (Use π = 22 ) 7
• 2. ppr maths nbk 3.Diagram 3 shows a cylinder. The shaded area with the shape of a hemisphere of radius 3 cm was removed. 7 cm Diagram 3 Find the volume , in cm³ , of the remaining solid. ( Use π = 22) 7 4.Diagram 4 shows a solid formed by joining a cone and a hemisphere. The diameter of the hemisphere is 10 cm and the slant height is 13 cm. Diagram 4 Calculate the volume , in cm³, of the solid
