Question

Volume of a hemisphere is 1800 pie cubic cm. find it radius

Answer 1

$\huge{\mathbb{\underline{\green{AnSwEr}}}}$

Volume of hemisphere =

$\frac{2}{3} \pi {(r)}^{3}$

$= > 1800\pi = \frac{2}{3} \pi {(r)}^{3} \\ = > 1800 = \frac{2}{3} {(r)}^{3} \\ = > 1800 \times \frac{3}{2} = {r}^{3} \\ 2700 = {r}^{3} \\ = > r = ± \sqrt[3]{2700} \\ = > r = ±30 \\ = > r = 30 \: cm$

HOPE THIS HELPS YOU!!!!!!!!!

Answer 2

Given:

• The volume of the Hemisphere = 1800π

Need To Find :

• The Radius of the Hemisphere ?

Solution:

As we know that,

⋆ volume of hemisphere = 2/3πr³

Putting the values,

➜ 1800π = 2/3πr³

➜ r³ = 1800π × 3/2π

➜ r³ = 900 × 3

➜ r³ = 2700

➜ r = 30 cm

Hence,

The radius of the Hemisphere is 30 cm.
