Question

If the volume of the cylinder is 68.75 cu.cm and it's radius is 2.5 cm then find its height

Answer 1

given volume of the cylinder = 68.75cm³

radius of the cylinder = 2.5cm

height = ?

formula to find the volume of a cylinder is πr²h

therefore πr²h = 68.75cm³

➡ 22/7 × 2.5 × 2.5 × h = 68.75cm³

➡ 137.5/7 × h = 68.75cm³

➡ h = 68.75 × 7/137.5

➡ h = 3.5cm

hence, the height of the cylinder is 3.5cm

Answer 2

Answer:

Step-by-step explanation:

given volume of the cylinder = 68.75cm³

radius of the cylinder = 2.5cm

height = ?

formula to find the volume of a cylinder is πr²h

therefore πr²h = 68.75cm³

➡ 22/7 × 2.5 × 2.5 × h = 68.75cm³

➡ 137.5/7 × h = 68.75cm³

➡ h = 68.75 × 7/137.5

➡ h = 3.5cm

hence, the height of the cylinder is 3.5cm
