Question

Радиус шара R=3 м. Найти объем шара и площадь его поверхности.

Answer 1

V = 4/3 * π * R^3

V = 4/3 *π * 3^3

V = 4/3 * π * 27

V = 36π см^3

S = 4πR^2

S = 4*π*3^2

S = 36π см^2

Answer 2

Calculating the Volume and Surface Area of a Sphere

To calculate the volume and surface area of a sphere with a radius of 3 meters, we can use the following formulas:

1. Volume of a Sphere: - The formula for the volume of a sphere is given by V = (4/3) * π * r^3, where V is the volume and r is the radius of the sphere.

2. Surface Area of a Sphere: - The formula for the surface area of a sphere is given by A = 4 * π * r^2, where A is the surface area and r is the radius of the sphere.

Calculation

Using the given radius R = 3 m, we can calculate the volume and surface area of the sphere:

1. Volume: - V = (4/3) * π * (3)^3 - V = (4/3) * π * 27 - V = 36π cubic meters

2. Surface Area: - A = 4 * π * (3)^2 - A = 4 * π * 9 - A = 36π square meters

Therefore, the volume of the sphere is 36π cubic meters and the surface area of the sphere is 36π square meters.

These calculations are based on the standard formulas for the volume and surface area of a sphere, and the results are in accordance with these formulas
