1 The Sphere The Cone Any Prisms Volume of Solids Int 2 Composite Prisms

2 Starter 5 cm 2.5 cm 3 cm 4 cm 3 cm Int 2

3 Volume of a Sphere Int 2 r D D = diameter Q.If the above sphere has radius 10cm. Calculate its volume.

4 Starter Int 2 D = 6 cm r D

5 Q.If the above cone has radius 15cm and height of 10 cm.Calculate its volume. Volume of a Cone Int 2 r h

6 Int 2 Definition : A prism is a solid shape with uniform cross-section Cylinder (circular Prism) Pentagonal Prism Triangular Prism Hexagonal Prism Volume = Area of Cross section x length Volume of Solids

7 Int 2 Definition : A prism is a solid shape with uniform cross-section Triangular Prism Volume = Area x length Q. Find the volume the triangular prism. 20cm 2 10cm = 20 x 10 = 200 cm 3 Volume of Solids

8 Int 2 Definition : A prism is a solid shape with uniform cross-section Volume = Area x length Q. Find the volume the hexagonal prism. 43.2cm 2 20cm = 43.2 x 20 = 864 cm 3 Hexagonal Prism Volume of Solids

9 Starter Int 2 D = 6 cm h = 10 cm r h

10 Volume of a Solid Int 2 Composite volume is simply volumes that are made up from basic volumes. r D r h Volume = Area x length

11 Volume of a Solid Int 2 Q. Find the volume the composite shape. Composite volume is simply volumes that are made up from basic volumes. Volume = Cylinder + half a sphere h = 6m r 2m ½ sphere Cylinder

12 Volume of a Solid Int 2 Q. This childs toy is made from 2 identical cones. Calculate the total volume. Composite Volumes are simply volumes that are made up from basic volumes. Volume = 2 x cone r = 10cm h = 60cm One cone Two cone
