Question

7. The radius of the base of a right circular cylinder is 4 cm and height is 2
melting this cylinder, how many right circular cylinder having radius 2cm
height
$1\times \frac{1}{2}$
cm can be made?​

Answer 1

$\pi \times {2}^{2} \times \frac{1}{2} \times \\ number \: of cylinders= 32\pi \\ so \: number \: of \: cylinders = \frac{32 \times \pi \times 2}{4 \times 1\times \pi } \\ so \: number \: of \: cylinders = 16.$

Step-by-step explanation:

Volume of the cylinder = π r² h,

= π × (4)²×2,

= 32π.

So, volume of the other cylinder= 32π,

Then radius of that cylinder = 2 cm,

and height of that cylinder= 1/2 cm.

So, volume of the new cylinder= π r²h,

= 32π,

So,
