Step-by-step explanation:
Q. A right circular cylinder has a height of 1 m and a radius of 35 cm. Find the volume of the cylinder.
Solution:
Given:
Height of the cylinder, h = 1 m
Radius of the cylinder, r = 35 cm = 0.35 m
To Find:
(i) Volume of the cylinder, V = ?
(ii) Curved Surface Area of the cylinder, CSA = ?
Formula:
(i) V = πr²h
(ii) 2πrh
Solution:
(i) Volume of the cylinder = πr²h
V = 22/7 * (0.35)² * 1
V = 22/7 * 0.35 * 0.35 * 1
V = 22/7 * 35/100 * 35/100 * 1
V = 22 * 35 * 35 / 7 * 10000
V = 22 * 35 * 5 / 10000
V = 3850 / 10000
V = 0.3850 ≈ 0.39 m³
(ii) Curved Surface Area of the cylinder = 2πrh
CSA = 2 * 22/7 * 0.35 * 1
CSA = 2 * 22/7 * 35/100 * 1
CSA = 2 * 22 * 35 / 7 * 10000
CSA = 2 * 22 * 5 / 10000
CSA = 220 / 10000
CSA = 0.0220 ≈ 0.02 m²
Ans. The Volume and the Curved Surface Area of the cylinder are 0.39 m³ and 0.02 m² respectively.
