Radius r = 7 cm, height h = 10 cm, and value of π = 22/7.

Since the radius is 7, the area of the base ($\pi r^2$) simplifies easily to $22/7 imes 49 = 154$. Multiplying by height $10$ simply adds a zero to get $1540$.

Students often use the diameter instead of the radius or mistake the surface area formula ($2\pi rh + 2\pi r^2$) for the volume formula ($\pi r^2 h$).

This concept is foundational for 'Surface Area and Volume' problems in competitive exams. Always remember that volume is always measured in cubic units ($cm^3$), which helps eliminate incorrect options in a hurry.
