Question

Circumference of the base of a right circular cylinder is 44 cm and its height is 15 cm. The volume (in cm) of the cylinder is (Take π = 22/7)
1. 770
2. 1155
3. 1540
4. 2310

Answer 1

Correct Answer - Option 4 : 2310

Given

Height = 15 cm 

Formula used:

The volume of the cylinder = π × r² × h  (Where, r = The radius of the cylinder and h = The height of the cylinder)

Circumference of the base of a right circular cylinder =  2πr

Calculation:

According to the question,

Circumference of the base of a right circular cylinder =  2πr

⇒ 44 = 2 × 22/7 × r

⇒ r = 7 cm

Now,

The volume of the cylinder = π × r2 × h

⇒ (22/7) × 7 × 7 × 15 = 2310 cm³

∴ The volume of the cylinder is 2310 cm³.
