1. find the volume of a cylinder with a radius of 0.5 mm and a height of 1.7 mm. round to nearest tenth 2. find the volume of a cylinder with a diameter of 4 mm and a height of 8 mm. round to nearest tenth. 3. find the volume of a cone with a diameter of 11 mm and a height of 11.2 mm. round to the nearest tenth. me quickly

Formala:

Volume of a cylinder = πr²h
Volume of a cone = 1/3 πr²h


Question (1):

Volume of the cylinder = π (0.5)² (1.7) = 1.3mm (nearest tenth)

1.3mm


Question (2):

Radius = 4 ÷ 2 = 2mm
Volume of the cylinder = π (2)² (8) = 100.5mm (nearest tenth)

 100.5mm 


Question (3):

Radius = 11 ÷ 2 = 5.5 mm
Volume of the cylinder = 1/3 π (5.5)² (11.2) = 354.8mm (nearest tenth)

  354.8mm

21/2 or 5/2
