Question

Радиус зрительного зала цирка в 2 раза больше радиуса манежа и на 12 метров меньше радиуса фойе известно что диаметр манежа 13.узнай чему равен диаметр здания цирка

Answer 1

Радиус зрительного зала 26
радиус фойе 38
радиус манежа 13
радиус здания получается 26+38+13 = 77

Answer 2

Calculation of the Diameter of the Circus Building

To find the diameter of the circus building, we need to use the given information about the radius of the auditorium, the arena, and the foyer.

Let's denote the radius of the auditorium as R_a, the radius of the arena as R_m, and the radius of the foyer as R_f.

According to the given information: - The radius of the auditorium is 2 times larger than the radius of the arena: R_a = 2 * R_m. - The radius of the foyer is 12 meters smaller than the radius of the arena: R_f = R_m - 12.

We also know that the diameter of the arena is 13 meters.

To find the diameter of the circus building, we can use the formula for the diameter of a circle, which is twice the radius:

D = 2 * R

Let's substitute the values we have into the formula:

D_a = 2 * R_a (diameter of the auditorium)

D_m = 2 * R_m (diameter of the arena)

D_f = 2 * R_f (diameter of the foyer)

We are looking for the diameter of the circus building, which is the sum of the diameters of the auditorium, arena, and foyer:

D_circus = D_a + D_m + D_f

Substituting the formulas for the diameters, we get:

D_circus = 2 * R_a + 2 * R_m + 2 * R_f

Now, let's substitute the given values into the equation and calculate the diameter of the circus building.

Given: - Diameter of the arena (D_m) = 13 meters

Calculations: - Radius of the arena (R_m) = D_m / 2 = 13 / 2 = 6.5 meters - Radius of the auditorium (R_a) = 2 * R_m = 2 * 6.5 =
