Question

The volume of the cylinder having base area as $20c{m}^2$ and height as 4 cm is equal to

• A. $60c{m}^3$
• B. $70c{m}^3$
• C. $80c{m}^3$
• D. $90c{m}^3$

Answer 1

The correct option is C $80c{m}^3$

Volume of the cylinder (V) is given by length $\times$ breadth $\times$ height.
$\Rightarrow$ V = Base area$\times$height
$\Rightarrow$ V = $20c{m}^2$$\times$ 4 cm
$\Rightarrow$ V = $80c{m}^3$
