See a solution process below:

The formula for the volume of a sphere is:

#V_s = 4/3pir^3#

Substituting #50"m"# for #r# and #3.14# for #pi# and calculating #V_s# gives:

#V_s = 4/3 xx 3.14 xx (50"m")^3#

#V_s = 4/3 xx 3.14 xx 125000"m"^3#

#V_s = 4/3 xx 392500"m"^3#

#V_s = 1570000/3"m"^3#

#V_s = 523333.33"m"^3#

Or

#523,333.33# cubic meters
