The main show tank has a radius of 60 feet and forms a quarter-sphere. what is the volume of the quarter-sphere shaped tank? rou
schepotkina [342]
By definition, the volume of a quarter of a sphere is given by:
 V = (1/4) * (4/3) * (\pi) * (r ^ 3)

 Where,
 r: sphere radius
 Substituting values we have:
 V = (1/4) * (4/3) * (3.14) * (60 ^ 3)

 Making the corresponding calculation we have:
 V = 226080 feet ^ 3
 Answer:
 
The volume of the quarter-sphere shaped tank is:
 
V = 226080 feet ^ 3
