Question

9.The diameter of a cylinder is 14 cm and its height is 7 cm then volume of cylinder​

Answer 1

Answer:

1078 cm3

Step-by-step explanation:

volume of cylinder is πr2h

and in this question we have diameter of cylinder so we can find radius (r) = 14/2 = 7 cm

and we have height also (h) = 7cm

now put these values in the formula

= π×7×7×7 = 22/7×7×7×7

= 22×49

=1078 cm3

Answer 2

Given :

⬤ Diameter of Cylinder = 14 cm

⬤ Height of Cylinder = 7 cm

To Find :

⬤ Volume of Cylinder .

Formula Used :

$\sf[\:{Volume\:of\:Cylinder=\pi{r}^{2}h}\:]$

Solution :

First , We need to calculate the Radius of the Cylinder . Hence ,

• Diameter = 14 cm
• Radius = 14/2 = 7 cm

According to the Formula :

πr²h

22/7 × 7 × 7 × 7

154 × 7

1078

Therefore , The Volume of the Cylinder is 1078 cm² .
