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 = 22/7)

Correct option is B

Given:
Radius of cylindrical tank, r = 7 m
Height of tank, h = 9 m
Formula Used:
Volume (capacity) of a cylinder = π r² h
Solution:
V = π × 7² × 9
= $$\frac {22}7$$​ × 49 × 9
= 441$$\times \frac {22}{7}$$​ m³
= 63 × 22
= 1386 m³
