Question

volume of a cone is 6280 cubic cm and the base radius of the cone is 30 cm.find it's perpendicular height. (pie = 3.14)
plz answer this fast

Answer 1

the height of the cone is 6.45


not sure!!!!

Answer 2

$volume \: of \: cone = \frac{1}{3 } \pi{r}^{2} h = 6280$
$so \\ h = \frac{6280 \times 3}{30 \times 30 \times 3.14}$
So
$h = 6 \frac{2}{3} cm$
