Answer 1

Ответ:

Пошаговое объяснение:

Объем шара равен: V=(4/3)*π *R³=(4/3) *3,14* 18,7³ ≈  27377,1 см³

Answer 2

Calculation of the Volume of a Sphere

To calculate the volume of a sphere, we can use the formula:

V = (4/3) * π * r^3

where V is the volume, π is the mathematical constant pi (approximately 3.14), and r is the radius of the sphere.

Given that the radius of the sphere is 18.7 cm and the value of π is approximately 3.14, we can substitute these values into the formula to find the volume.

V = (4/3) * 3.14 * (18.7)^3

Calculating this expression will give us the volume of the sphere. Let's do the math:

V ≈ 4/3 * 3.14 * (18.7)^3

Using a calculator, we find that the volume of the sphere is approximately 24,493.3 cm³.

Therefore, the volume of the sphere with a radius of 18.7 cm, rounded to the nearest tenth, is 24,493.3 cm³.
