Question

find the volume of cylinder with diameter = 70cm and height = 2000cm

Answer 1

Given

• Diameter of cylinder = 70cm
• Height of cylinder = 2000cm

To find

• Volume of cylinder

Formula to find volume of cylinder

• πr²h

→ r is radius and h is height of cylinder

Solution

• Diameter = 70cm
• Radius = Diameter ÷ 2
• Radius = 70 ÷ 2 = 35

☯ Radius of the cylinder is 35cm

• Volume = πr²h
• Volume = ²²⁄₇ × 35 × 35 × 2000
• Volume = 3850 × 2000
• Volume = 7700000

☯ Volume of the cylinder with d = 70cm and h = 2000cm :-

• 7700000cm³
