Question

THE TOTAL SURFACE AREA OF HEMISPHERE IS 942CM²,THEN ITS VOLUME IS 

Answer 1

Answer:

2/3 pi r 3

Explanation:

Vol of hemisphere is 2095.23 cm 3

Answer 2

Total surface area of hemisphere = 942cm²

We know that,

TSA of a hemisphere = 3πr²

3 × 22/7 × r² = 942cm²

22/7 × r² = 942/3

r² = 314 × 7/22

r² = 2198/22

r  = √100

r = 10

radius of hemisphere is 10cm .

now,the volume of hemisphere.

Volume of hemisphere = 2/3 π r³

= 2/3 × 22/7 × (10)³

= 44/21 × 1000

= 44000/21

= 2095.23cm³

 the volume of hemisphere is 2095.23cm³.

hope this will be helpful for you.
