Question

Find the height of a cylinder of volume 200 cm3 and radius 4 cm.​

Answer 1

Answer:

volume of cylinder= 200cm³

radius= 4cm

height= ?

now,

volume of cylinder = πr²h

200cm³= 22/7 * (4)² * h

200*7=16*h

200 * 7 / 16 = h

12.5*7= h

87.5 = h

therefore height of cylinder= 87.5cm

Answer 2

Answer:

the answer = 4 cm

Step-by-step explanation: given V = 200cm^3

                                            radius = 4cm

formula for cylinder volume = $\pi{r^2}h$

by making height as subject(getting formula for height), we get  $h = \dfrac{V}{\pi r^{2}}$

so, $V = 200cm^3$

     $\pi{r^2} = 50cm^2$

h = (200/50)cm

  = 4cm
