just answer it ax⁴+bx³+cx²+dx+f=0

Answer 1

Step-by-step explanation:

Answer:

$\huge{\dag}{\underline{\boxed{\sf{\red{Answer:- }}}}}$

Radius of base of cone =3r

Height of cone = radius of base of cone =3r

Volume of cone

$\frac{1}{3} \pi {r}^{2} h = \frac{1}{3} \times (3r) ²×3r \\ \frac{1}{3} \times \pi \times 27 {r}^{3} \\ 9\pi {r}^{3}$

Therefore the volume of cone = 9πr³
