Answer 1

the height of big cylinder is 20 cm and the diameter is 56 cm radius is 28 cm
The height of smaller cylinder is 5 cm
and radius is 7 cm.
Let the numbers of smaller cylinder be 'x'
Volume of cylinder
$\pi {r}^{2} h$
R be 28 cm
r be 7 cm
$\frac{22}{7} (28) {}^{2} (20) = x( \frac{22}{7} \times ( {7}^{2})(5)) \\ 28 \times 28 \times 20 = x \times 7 \times 7 \times 5 \\ x = \frac{28 \times 28 \times 20}{7 \times 7 \times 5} \\ x = 64$
the number of smaller cylinder that can be made out of bigger cylinder are 64.
