Question

Утной стрелки? 184. 1) Диаметр Луны 3476 км. Вычислите длину экватора Луны.2) Диаметр основания юрты равен 8 м. Найдите площадь основанияюрты.​

Answer 1

Ответ:

Пошаговое объяснение:

1)d=3476 км  C-?

Длина экватора - это есть  длина окружности

С=π*d,  

C=3,14 * 3476 = 10914,6 км

2) d= 8 м.  S-?

Площадь основания юрты  : S=π*R²

R=d/2 = 8/2 =4 м

S= 3,14 * 4²= 50,24 м²

Answer 2

Calculations for Lunar Equator and Yurt Base

1) Calculating the Length of the Lunar Equator: - The diameter of the Moon is 3476 km. - To find the length of the lunar equator, we can use the formula: Equatorial circumference = π * diameter. - Substituting the given diameter of the Moon into the formula: - Equatorial circumference = π * 3476 km. - Calculating the equatorial circumference of the Moon: - Equatorial circumference ≈ 3.1416 * 3476 km. - Equatorial circumference ≈ 10,917.97 km. - Therefore, the length of the equator of the Moon is approximately 10,917.97 kilometers.

2) Finding the Area of the Base of the Yurt: - The diameter of the base of the yurt is given as 8 meters. - The formula to find the area of the base of a yurt is: Area = π * (radius)^2. - Given that the diameter is 8 meters, the radius is half of the diameter, so the radius is 4 meters. - Substituting the radius into the formula: - Area = 3.1416 * (4 meters)^2. - Calculating the area of the base of the yurt: - Area ≈ 3.1416 * 16 square meters. - Area ≈ 50.2656 square meters. - Therefore, the area of the base of the yurt is approximately 50.2656 square meters.
