If the radius of a cylindrical tank is 7 m and its height is 9 m, then find the capacity of the tank (in m3 ). (Use π = )
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1386.
Volume = π × r² × h
radius (r) = 7 m
Height (h) = 9 m
π = 22/7
Volume = (22/7) × 7² × 9
= (22/7) × 49 × 9
= 22 × 7 × 9 = 1386 m³
