Question

what is the formula of cone

Answer 1

heya

volume of cone=1/3πr^2h .

l.s.a of cone =πrl.

t .t. s.a =πrl+πr^2

so, πr(l+r) = total surface area of cone

hope it help you.

$\implies \: tsa \: = \: \pi \: r \: (l + r) \\ \\ \implies \: csa \: = \pi \: r \: l\\ \\ \implies \: volume \: = \frac{1}{3} (\pi \: {r}^{2} h)$
