Find the volume of a sphere that has a diameter of 9 feet. volume= blank ft^3 (use 3.14 for pi and round your answer to the nearest tenth.)

Diameter = 9feet
Radius = 4.5 feet (radius is half of the diameter)

Formula for the volume of a sphere is:
V = (4pi*r³)/3

Plug in your radius:

V = (4π * (4.5)³) / 3

V = 121.5(3.14)
V = 381.5

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
