Answer 1

Explanation:

The volume of a solid hemisphere is 1152 π cm3. Find its curved surface area.

Solution:

Here, volume of hemisphere = 1152 π cm3

∴ 23πr3 = 1152

⇒ r3 = (12)3 π

⇒ r1152×32 = 1728

⇒ r3 = (12)3

Now, curved surface area = 2πr2

= 2 × π × (12)2 = 288π cm2

Solution:

Here, volume of hemisphere = 1152 π cm3

∴ 23πr3 = 1152

⇒ r3 = (12)3 π

⇒ r1152×32 = 1728

⇒ r3 = (12)3

Now, curved surface area = 2πr2

= 2 × π × (12)2 = 288π cm2
