Question

The circumference of the base of a right circular cylinder is 44 cm and its height is 15 cm. The volume (in cm³) of the cylinder is \(\left( use \ \pi = \dfrac{22}{7} \right)\)
1. 770
2. 1155
3. 1540
4. 2310

Answer 1

Correct Answer - Option 4 : 2310

Given:

Circumference = 44 cm

Height of cylinder = 15 cm

Formula used:

Circumference of base of cylinder = 2 π R

Volume of cylinder = π R² h

Where, 

R = Radius of the base of cylinder

h = Height of cylinder

Calculations:

Let the radius of the base of cylinder be R

⇒ 2 × (22/7) × R = 44

⇒ R = 7 cm

Volume of cylinder = (22/7) × 7 × 7 × 15

⇒ 22 × 7 × 15

⇒ 2310 cm³

∴ The volume of cylinder is 2310 cm3
