Answer:

V = 321 m^3

Step-by-step explanation:

Volume of a sphere

V = 4/3 pi r^3

The radius is equal to

r = d/2

r = 8.5/2 =4.25

V =4/3 (3.14) (4.25)^3

V =321.3920833 m^3

Rounding to the nearest whole number

V = 321 m^3

Answer:

V = 321 m^3

V = 4/3 pi r^3      diameter is double of radius (radius is half of diameter)

V = 4/3 pi (4.25)^3

V= 75.66 meters squared (rounded)
