Question

A cone with base radius 7 cm has a volume of 308 cm cube find the vertical height of the cone take π 22/7​

pls now

Answer 1

h=6.003 cm

Explanation:

`(1)/(3) \pi {r}^(2) h \: \: is \: the \: volume \: of \: cone`

1/3×22/7×7×7×h=308

h=308/51.3

Answer 2

h = 6 cm

Explanation:

r = 7 cm

Volume of cone = 308 cm³

`(1)/(3)\pi r^(2)h=308\\\\\\(1)/(3)*(22)/(7)*7*7*h=308\\\\\\h=(308*3*7)/(22*7*7)\\\\\\h=2*3`

h = 6 cm
