Answer:
Explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
1) diameter = 4 inches
Radius = diameter/2 = 4/2 = 2 inches
Height = 10 inches
Volume = 3.14 × 2² × 10 = 125.6inches³
2) Radius = 20 cm
Height = 50 cm
Volume = 3.14 × 20² × 50 = 62800 cm³
3) diameter = 16 mm
Radius = diameter/2 = 16/2 = 8 mm
Height = 10 mm
Volume = 3.14 × 8² × 10 = 2009.6 mm³
4) Radius = 9 feet
Height = 9 feet
Volume = 3.14 × 9² × 9 = 2289.06 ft³
