Question

volume of a cone is 6280 cm qube and its base radius is 20cm . then find its perpendicular height

Answer 1

$\huge\mathcal{Heya}$

$\mathsf\red{Given \ :-}$
$<b>$
Volume of the cone = 6280 cm³

Base radius = 20 cm

Now,

Using formula,

Volume of cone = 1 / 3 × πr²h

Here, r = Base radius

And

h = Height

Substituting values in the formula, we get

6280 = 1 / 3 × 22 / 7 × (20)² × h

h = (6280 × 7 × 3) / (1 × 22 × 20 × 20)

h = 131880 / 8800

h = 14.98 cm

h = 15 cm (Approx)

$\huge\mathbb{Hope \ this \ helps.}$

Answer 2

volume of the cone =6280cm cube
base radius =20 cm
volume of the cone =
$\pi \: r ^{2} h$
6280cm=22/7×20×20×h
(6280cm ×7)/(22×20×20)=h
=0.73cm
