Question

Find the density of a 5 - kg solid cylinder that is 10 cm tall and has a radius of 3 cm.​

Answer 1

Answer:

mass of cylinder is 5 kg.=5000grams. Density=mass/volume. volume of given cylinder is 3.14*3*3*9cm cube. hence density is 5000/3.14*3*3*9 gm per centimetre cube.

Answer 2

$\huge\bf\underline{\underline{Given:}}$

$Mass\: of \:cylinder = 5kg = 5000g\\</p><p>Radius\: of\: cylinder = 3cm\\</p><p>Height \:of\: cylinder = 10cm$

$\huge\bf\underline{\underline{To\:Find:}}$

$Density \:of\: cylinder$

$\huge\bf\underline{\underline{Solution:}}$

$\boxed{\bold{\green{Volume\:of\: Cylinder= \pi {r}^{2} h}}}$

$Volume= 3.14 \times {3}^{2} \times 10 \\ Volume = 31.4 \times 9$

$\boxed{\bold{\red{Volume = 282.6c {m}^{3}}}}$

$\boxed{\bold{\green{Density= \frac{Mass}{Volume}}}}$

$Density = \frac{mass}{volume} \\\\ Density= \frac{5000}{282.6}$

$\boxed{\bold{\red{Density =17.69g/cm^3}}}$
