Question

Three cylinders have a height of 8cm. Cylinder 1 has a radius of 1cm. Cylinder 2 has a radius of 2cm. Cylinder 3 has a radius of 3cm. Find the volume of each cylinder.

Answer 1

Volume of Cylinder 1 = π×r×r×h

= 22÷7×1×1×8

= 25.13cm

Volume of Cylinder 1 = π×r×r×h

= 22÷7×2×2×8

= 100.53cm

Volume of Cylinder 1 = π×r×r×h

= 22÷7×3×3×8

= 226.19cm
