A water tank is shaped like a right circular cylinder with
a height of 10 cm and a base radius of 2.8 cm. What is its volume? (Use π = 22/7)Solution
ATQ,
Volume of right circular cylinder = π × radius² × height
= (22/7) × (2.8)² × 10
= (22/7) × 7.84 × 10
= (22 × 7.84 × 10) / 7
= (1724.8) / 7
= 246.4 cm³
