The circumference of the base of a cylindrical vessel is 132 cm and its height is 25 cm (use pi = 22/7).
Find the (i) Radius of the cylinder (ii) Volume of the cylinder
A cylinder shape is a three-dimensional solid figure which consists of two circular bases connected with two parallel edges.
Answer: The radius of the cylinder is 21 cm and the volume of the cylinder is 34650 cm3.
Let us find the radius and volume of the cylinder with the given parameters.
Explanation:
Given that, the circumference of the base is 132 cm.
2 × π × r = 132
r = 132 / (2 × π)
r = 66 / π = 66 / (22/7) = (66 × 7) / 22 = 3 × 7 = 21 cm
Hence, Radius = 21 cm
Height = h = 25 cm (given)
Volume of cylinder = π r2 h square units
= π (21)2 (25)
= (22/7) × (21) × (21) × 25
= 22 × 3 × 21 × 25
= 34650
Hence, Volume of the cylinder = 34650 cm3
Thus, the radius and volume of the cylinder with the given parameters are 21 cm and 34650 cm3 respectively.
