Question

sphere and cylinder are having same height and same radius then how many cylinders can be drawn from melting of sphere​

Answer 1

Let height and radius be 1.

So volume of sphere =

$\frac{4}{3} \pi {r}^{3}$

=

$\frac{4}{3} \times \frac{22}{7} \times {1}^{3}$

=

$\frac{88}{21}$

Now, volume of cylinder=

$\pi {r}^{2} h$

=

$\frac{22}{7} \times {1}^{2} \times 1$

=

$\frac{22}{7}$

Now, volume of sphere =volume of cylinder.

Therefore,

=

$\frac{88}{21} = \frac{22}{7}$

=

$88 \times 7 = 22 \times 21$

= 616=616

There answer is 1
