Answer 2

Answer:

$\red { weight \: of \: the \: solid \: cylinder }$

$\green { = 103.95 \:kg }$

Step-by-step explanation:

$Dimensions \: of \: a \: cylinder :$

$Radius (r) = 10.5 \:cm$

$Height (h) = 60\:cm$

$\boxed { \pink {Volume \: of \: a \: cylinder = \pi r^{2}h }}$

$V = \frac{22}{7} \times (10.5)^{2}\times 60$

$= \frac{22}{7} \times 10.5\times10.5\times 60$

$= 22 \times 1.5\times10.5\times 60$

$= 20790\: cm^{3}$

/* According to the problem given,

$1\:cm^{3} \: material \: weight = 5 \:gm$

$20790 \:cm^{3} \: cylinder \: material \: weight \\= 5 \times 20790 \\= 103950\:gm\\= 103.95\:kg$

Therefore.,

$\red { weight \: of \: the \: solid \: cylinder }$

$\green { = 103.95 \:kg }$
