Question

The volume of a cylindrical tank having radius and height as 7 cm and 10 cm respectively is equal to

• A. 1450 $c{m}^3$
• B. 1540 $c{m}^3$
• C. 1520 $c{m}^3$
• D. 1580 $c{m}^3$

Answer 1

The correct option is B 1540 $c{m}^3$

Volume of the cylinderical tank, V = $\pi \times r^2\times h$
where $r$ and $h$ are the radius and height of the tank respectively.

V = $\pi \times r^2\times h$
V = $\frac{22}{7}\times 7\times 7\times 10$
V = 1540 $c{m}^3$
