Question

Find the volume of cylinder whose base diameter is $140$ cm and height is $100$ cm.

• A. $154000{cm}^3$
• B. $1540000{cm}^3$
• C. $15400000{cm}^3$
• D. None

Answer 1

Answer: (B)

$1540000{cm}^3$

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

$d=140$cm and $h=100$cm

$\therefore r=70$,

Let $V$ be the volume of the cylinder

$V=\pi (70\times 70)\times 100$

$=\frac{22}{7}\times (70\times 70)\times 100$

$=220\times 7000$

$=1540000$ $c{m}^3$
