h Volume =  r 2 h The Volume of a Cylinder A cylinder is a prism with a circular cross-section. r2r2

10 cm The Volume of a Cylinder Calculate the volume of the following cylinders. 15 m 4.2mm 9.2 mm 3 cm 2 m V =  r 2 h =  x 3 2 x 10 = cm 3 V =  r 2 h =  x 2 2 x 15 = m 3 V =  r 2 h =  x x 4.2 = mm 3

V =  r 2 h =  x x 4 = m cm 1m 3 The Volume of a Cylinder Find the capacity (in litres) of the water storage tank. 4 m 6.2m 1 m 3 =100 x 100 x100 = cm 3 = litres V = litres (3 sf)

V =  r 2 h =  x x 3 = m 3 V = litres (3 sf) 100 cm 1m 3 The Volume of a Cylinder Find the capacity (in litres) of the water storage tank. 3 m 8.4m
