Volume of Curved Shapes
Activity
Cones and Spheres
Volume of a Cylinder
Volume of prisms
Volume of prism =
area of cross-section x depth
Know the volume of a cylinder, and use the formulae for volumes of cones and spheres.
Volume of a Cylinder
r = 17 m
V = Pi x 17 x 17 x 27
= 24513 m
3
r = 2 cm
V = Pi x 2 x 2 x 5
= 62.83 cm

Large Cylinder = Pi x 2 x 2 x 15
= 188.5
Small Cylinder = Pi x 1 x 1 x 15
= 47.12
Remaining = 188.5 - 47.12
= 141.38
