Worksheet on Volume of Cylinder for Class 1

Solved Questions of Volume of a Cylinder

1. Find the volume of a hollow cylinder whose outer radius is 5 m, inner radius is 4 m and height is 14 m. (Use π = 22/7).

a) 462 m³
b) 330 m³
c) 450 m³
d) 396 m³

Answer: d) 396 m³

Explanation: V = π (R² - r²) h
= 22/7 (5² - 4²) 14
= 22/7 (25 - 16) 14
= 22/7 x 9 x14
= 396 m³

So, the volume of the cylinder is 396 m³.

2. Find the approximate volume of the cylinder shown:

a) 3014 cm³
b) 2099 cm³
c) 1987 cm³
d) 1876 cm³

Answer: a) 3014 cm³

Explanation: V = πr²h
V = (3.14) (8 x 8) (15)
V = 3014.4 cm³

3. The volume of a cylinder is 440 cm³ and the height is 35 cm. Find the radius of the cylinder of a base.

a) 2 cm
b) 3 cm
c) 4 cm
d) 5 cm

Answer: a) 2 cm

Explanation: V = 440 cm³
h = 35 cm
V = πr² h
440 = (22/7) x r² x 35
r² = (440 x 7) / (22 x 35) = 3080/770 = 4
r = 2 cm

4. Calculate volume of the cylinder in which the height is given as 20 cm and the radius of the base is given as 14 cm. (Take π = 22/7)

a) 12320 cm³
b) 23120 cm³
c) 23210 cm³
d) 23201 cm³

Answer: a) 12320 cm³

Explanation: h = 20 cm
r = 14 cm

Volume of the cylinder, V = πr²h
V = (22/7) x 14 x 14 x 20
V = 12320 cm³

5. Calculate the height of a cylinder if its volume is 570 m³ and its radius is 4 m.

a) 11.34 m
b) 10.24 m
c) 9.8 m
d) 8.7 m

Answer: a) 11.34 m

Explanation: We have, V = 570 m³ and r = 4 m
Using the formula we have,
V = πr²h
h = V/πr²
h = 570/ (3.14 × 4 × 4)
h = 11.34 m
