A beach ball has a radius of 12 in.. How much air will the beach ball hold?
To determine how much air the beach ball will hold, we can calculate its volume. The volume of a sphere, such as a beach ball, is given by the formula:
V = (4/3) * π * r^3
Where:
V = volume
π (pi) ≈ 3.14
r = radius
In this case, the radius of the beach ball is given as 12 inches. So, substituting the value into the formula:
V = (4/3) * 3.14 * 12^3
Now, let's simplify the equation:
V = (4/3) * 3.14 * 1728
V = 7234.56
Therefore, the beach ball will hold approximately 7234.56 cubic inches of air.
well in cubic inches
Vol = (4/3) pi r^3
= (4/3) (3.14159) (1728)
