plz mark me brainliest and folow me plz and also give me thanks

Answer 2

Answer :

• Total surface area of hemisphere is 9.42cm²

Given :

• Radius = 3cm

To find :

• Total surface area of a solid hemisphere

Solution :

As we know that ,

• Total surface area of hemisphere = 3πr²

where, r is radius 3cm

》3 × 22/7 × 3 × 3

》9.42 cm²

Hence,Total surface area of hemisphere is 9.42cm²

More Explanation :

• Hemisphere is a 3D
• Curved surface area of hemisphere = 22πr²
• Total surface area of hemisphere = 3πr²
