Чему равна площадь стадиона ,имеющего форму окружности, если спортсмен пробегает с одной стороны на другую через центр стадиона со скоростью 10,8км/ч за 50 сек.

Answer 1

10.8 км/ч = 3 м/c
3*50=150 (м) - диаметр стадиона.
150/2=75 (м) - радиус стадиона.
S=Пr²=3.14*75²=17662.5 (м²)

Answer 2

Calculation of the Stadium Area

To calculate the area of a stadium in the shape of a circle, we need to know the radius of the circle. However, the given information does not provide the radius of the stadium. Therefore, it is not possible to determine the exact area of the stadium based on the given information.

If you have any additional information, such as the radius or diameter of the stadium, please provide it so that I can assist you further.
