Question

If the volume of the hemisphere is 18 pie thenwhat radius of hemisphere is'

Answer 1

Given :

Volume of the Hemisphere = 18π

To Find : Radius of the Hemisphere

Solution :

The volume of a hemisphere = ⅔πr³

⅔πr³ = 18π

r³ = 18π3/2π

r³ = 9×3

r³ = 27

r³ = 3³

r = 3

Radius of the Hemisphere is 3 units .

Thanks !!

Answer 2

Aɴsᴡᴇʀ:

• The radius of the Hemisphere = 3 cm

Gɪᴠᴇɴ:

• The volume of the Hemisphere = 18π

Nᴇᴇᴅ Tᴏ Fɪɴᴅ:

• The Radius of the Hemisphere = ?

Solution:

Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ ʜᴇʀᴇ:

• The volume of a hemisphere = 2/3πr³

Pᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇs

➦ 18π = 2/3πr³

➦ r³ = 18π × 3/2π

➦ r³ = 9 × 3

➦ r³ = 27

➦ r³ = 3³

➦ Radius = 3 cm

Tʜᴇʀᴇғᴏʀᴇ:

• The radius of the Hemisphere = 3 cm
