What is the volume of a hemisphere with a radius of 6.9 m, rounded to the nearest tenth of a cubic meter?

Question

 Need help ASAP, please

Answer 1

The volume of a sphere is (4/3)πr³.  The volume of a hemisphere is half of that, so 

 

V = (1/2) (4/3)πr³ 

 

V = (2/3)πr³

 

Plug in r = 6.9 m and get V in m³.
