Question

the volume of hemisphere is 1527.4cm^3.find the radius of the hemisphere to the nearest whole whole number.(take π to be 22/7)​

Answer 1

radius of the hemisphere = 9 cm approx

Explanation:

Volume of hemisphere =
`(2)/(3) \pi r^(3)`

1527.4 =
`(2)/(3) * (22)/(7) * r^(3)`

`(7*15274*3)/(2*22*10)` =
`r^(3)`

`(320754)/(440)` =
`r^(3)`

`r^(3)` = 729

r =
`\sqrt[3]{729}`

r = 9 cm approx.
