Question

The diameter of the base of a cylindric tank is 14 cm and its height is 17 cm. What is its volume?

Answer 1

SOLUTION :

The diameter of base of cylinder = 14 cm   (given)

The height of the cylinder = 17 cm      (given)

The radius of the cylinder = 14 ÷ 2 = 7 cm

[ ∴ As radius = diameter ÷ 2 ]

To be found :-

The volume of the cylinder

Formula for finding the volume of a cylinder = $\bf \pi r^{2}  h$  unit sq.

[ ∴ In which r is the radius and h is the height of the cylinder ]

= $\bf \frac{22}{7} \times (7)^{2} \times 17$  cm sq.

= $\bf 2618$   cm sq.

Hence,

Volume of the cylinder is 2618 cm sq.

Answer 2

SOLUTION :

$\red{\underline{\sf Given}}$

The diameter of the base of cylinder = 14 cm

And, The height of the cylinder = 17 cm  

So, we can get radius of the cylinder -

The radius of the cylinder =  = 7 cm

[ ∴ $\sf radius = \frac{diameter}{2}$ ]

$\huge{\underline{\sf \green{To}\ \red{be}\ \orange{found :-} }}$

The volume of the cylinder

Formula for finding the volume of a cylinder = πr²h unit sq.

[ ∴ In which 'r' is the 'radius' and 'h' is the 'height' of the cylinder]

= $\bf \frac{22}{7} \times (7)^{2} \times 17$  cm sq.

= 2618 cm sq.

Hence,

The Volume of the cylinder is 2618 cm sq.
