Answer 2

• Total surface area of hemisphere is 462 cm².

Step-by-step explanation:

To find:-

• Total surface area of hemisphere.

Solution:-

Given that,

Diameter of hemisphere is 14 cm.

Radius = Diameter/2

= 14/2

= 7

Radius of hemisphere is 7 cm.

Total surface area of hemisphere = 3πr²

➝ 3 × 22/7 × 7 × 7

➝ 3234/7

➝ 462

Therefore,

Total surface area of hemisphere is 462 cm².
