Question

if the radius of a cylinder is 14cm and height is 5 cm,then find the volume of this cylinder

​

Answer 1

Answer:

Right cylinder

Solve for volume

V≈3078.76cm³

r Radius

14

cm

h Height

5

cm

Answer 2

• Given

• Radius of a cylinder = 14 cm
• Height of a cylinder = 5 cm

• To find

• Volume of cylinder

• Solution

Volume of a cylinder = πr²h

Substitute the given values,

⇒ 22/7 × 14 × 14 × 5

⇒ 3080 cm³

• Volume of cylinder = 3080 cm³
