Following are the responses to the given point:

Explanation:

$r=8\ cm\\\\h=10 \ cm\\\\l=\sqrt{r^2+h^2}=\sqrt{10^2+8^2}=\sqrt{100+64}=\sqrt{164}$

Area of cone:

$A=\pi r l +\pi r^2\\\\$

$=\pi\times 8\times \sqrt{164} +\pi \times 8^2\\\\=\frac{22}{7}\times 8(\sqrt{164} + 8)\\\\= 522.92\ cm^2\\\\=522.9 \ cm^2\\$

Volume of cone:

$v=\frac{1}{3}\pi r^2 h\\\\$

$=\frac{1}{3} \times\frac{22}{7} \times 8^2 \times 10\\\\=670.2\ cm^3\\\\$

Calculating the empty space:

$V' =\text{cylinder volume- cone volume}= \pi r^2h-\frac{1}{3} \pi r^2h=\frac{2}{3} \pi r^2h\\\\$

$V'=2 \times \text{cone volume} \\\\$

$=2 \times 670.2\ cm^2\\\\=1340.4\ cm^2$

Mamont248 [21]

It can mean many things to certain people. However I feel like it means don’t let other people tell you your future instead follow “God”.
