Question

Volume of a cone is 6280 cubic cm and base radius of the cone is 30 cm. Find its perpendicular height. (phi=3.14

Answer 1

Answer:

6.66 cm.

Step-by-step explanation:

Formula of volume of cone = $\frac{1}{3} \pi r^{2} h$

Where r = radius

H= Perpendicular Height

Radius = 30 cm

Volume = 6280 cubic cm.

So,  $6280=\frac{1}{3} \times 3.14 \times  (30)^{2} \times h$

$18840= 3.14 \times 900 \times h$

$\frac{18840}{3.14 \times 900}= h$

$6.66= h$

Hence the perpendicular height of the cone is 6.66 cm.
