Question

What is the volume of a cylindrical bottle having base radius 7 cm and height 20 cm.

• A. $3080{\text{cm}}^3$
• B. $3180{\text{cm}}^3$
• C. $3040{\text{cm}}^3$
• D. $3140{\text{cm}}^3$

Answer 1

The correct option is A

$3080{\text{cm}}^3$

Given: r = 7 cm, h = 20 cm

Volume $=\pi r^{2}h$

$=\frac{22}{7}\times 7\times 7\times 20$

$=3080{\text{cm}}^3$

Hence Volume of the cylindrical bottle$=3080{\text{cm}}^3$
