Question

find the total surface area of a hemisphere of radius 10 cm.

​

Answer 1

Answer:

Total surface area of a hemisphere is 3πr2 where 'r' is the radius of the hemisphere and ′π′ is equal to 22/7 or 3.14. We are given that the radius of the hemisphere is 10cm. r=10cm. Therefore, the total surface area of a hemisphere with radius 10cm is 942.857 square centimeters

Answer 2

Question:-

• Find the total surface area of a hemisphere of radius 10 cm.

Given:-

• Radius of a hemisphere = 10 cm

Tofind:-

• T.S.A of the hemisphere

Solution:-

• Radius = 10 cm
• π = 3.14

→ T.S.A of hemisphere = 3πr²

→ T.S.A of hemisphere = 3×3.14×10×10

→ T.S.A of hemisphere = 3 × 314

→ T.S.A of hemisphere = 942 cm²

Hence,

• T.S.A of hemisphere is 942 cm²
