Question

Футбольный мяч имеет диаметр 30 см. Какой обьём воздуха находиться в мяче ? ( П = 3,14 )

Answer 1

Объем шара 4/3πR³
4/3*3.14*15³=14130см³

Answer 2

Calculating the Volume of Air in a Football

To calculate the volume of air in the football, we can use the formula for the volume of a sphere, which is given by:

V = (4/3) * π * r^3

Where: - V is the volume of the sphere - π (pi) is approximately 3.14 - r is the radius of the sphere

Given that the diameter of the football is 30 cm, we can calculate the radius (r) as half of the diameter, which is 15 cm.

Calculation

Using the formula for the volume of a sphere, we can calculate the volume of air in the football:

V = (4/3) * π * 15^3

V ≈ (4/3) * 3.14 * 3375

V ≈ 4.1867 * 3375

V ≈ 14137.1675 cm^3

Therefore, the volume of air in the football is approximately 14137.1675 cm^3.
