Question

The volume of a right circular cylinder of base radius 35 cm is 154 dm^3 . It's height will be

Answer 1

Here is your answer buddy,

$\textbf{Given}$

Volume of the cylinder = 154$cm^{3}$
Radius = 35 cm

$\textbf{Now}$

We know that,

Volume of a Cylinder is = $\pi × r^{2} × h$

Therefore,

$\pi × r^{2} × h$ = 154

=> $r^{2} × h$ = 154 × $\frac{22}{7}$

=> $r^{2} × h$ = 22 × 22

=> $h$ =$\frac{22 × 22}{35 × 35}$ (as radius is given = 35)

=> $h$ = $\frac{484}{1225}$

$\textbf{Therefore,}$

The height of the cylinder is 484/1225

Hope this helps you.

Answer 2

Answer:

we have to convert 154dmcube into cm cubic form

so we get answer by converting 154dm into cm is 154000 (1dm =1000cm)

now the volume of the cylinder is 154000

vol. of cylinder =πr^2h

154000=22/7×35×35×h

154000=22×5×35×h (by cutting)

154000/22×5×35=h

we get 40 cm

therefore the height is 40cm
