Question

find the volume of a cylinder whose base radius is 3 cm and height is 7 cm​

Answer 1

Answer:

r = 3cm

h= 7cm

Volume of cylinder =πr²h

volume =22/7 × (3)²×7

=22×9

volume of cylinder=198cm³

Answer 2

The correct answer is 198 $cm^{3}$.

Given: Radius = 3 cm.

Height = 7 cm.

To Find: The volume of cylinder.

Solution:

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

= $\frac{22}{7}*3^{2} *7$

= 22*$3^{2}$

= 22*9

= 198 $cm^{3}$

Hence, the volume of cylinder is 198 $cm^{3}$.
