Explanation:

V = (4/3) *  * r³ ;

Given: diameter, "d" = "8 m" ;

radius, "r" = 8 m / 2 = 4 m " 
    
V = (4/3) *  * r³

V = (4/3) *  *(4m)³

V = (4/3) * (3.14) * 4³ * m³  ; 

V = (4/3) * (3.14) * (4*4*4) * m³ ;

V = (4/3) * (3.14) * (64) * m³ ;

V = 267.9466666666666667 m³ ;

round to: " 267.95 m³ " .
