Volume is 4/3(3.14)(r)^2 
the radius is 5.2 ft
        
             
        
        
        
Answer:

Step-by-step explanation:
a hemisphere is half a sphere.
And if the formula for the volume of a sphere is:

we must calculate the volume of the sphere and in the end divide by two to find the volume of the hemisphere. 
Since the radius is: 

substituting this into the formula for volume: 

this is the volume of the total sphere, thus the volume of a hemisphere is:

rounding to the nearest tenth:
