Question

the volume of cone is 462 M cube its base radius is 7 metres find its height

Answer 1

Answer:

h = 9m.

Step-by-step explanation:

Given, radius = 7 m.

Given, volume of cone = 462 m³.

⇒ (1/3) * πr²h = 462

⇒ (1/3) * (22/7) * (7)² * h = 462

⇒ (1/3) * 22 * 7 * h = 462

⇒ 154 * h = 1386

⇒ h = 9 m.

Therefore, height = 9m.

Hope it helps!

Answer 2

It is given that,

Volume of Cone (V) = 462 m^3
& Radius (R) = 7 m

$= > \: v \: = 462 \: {m}^{3}$

$= > \frac{1}{3} \times\pi \: \times {r}^{2} \times h \: = 462 {m}^{3}$

$= > \: \frac{1}{3} \times \frac{22}{7} \times 7 \times 7 \times h \: = 462$

$= > \: 51.3 \times h \: = 462$

$= > \: h \: = \frac{462}{51.3} \: m$

$= > \: h \: = 9 \: m \:$
