What is the volume of a hemisphere with a diameter of 4.9 m, rounded to the nearest tenth of a cubic meter?

Question

Need to know asap thank u and If u dont know its okay 

Answer 1

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

 

V = (1/2)(4/3)π(4.9³)

V = 246.403 m³

 

I'll let you do the rounding.
