Вопрос школьника по предмету Геометрия
Найдите радиус окружности длинной 36п см
Ответ учителя по предмету Геометрия
длина окружности вычисляется по формуле:
с=2ПR,
где c — длина окружности
R — радиус окружности
выразим R:
R= c/2П=36П/2П= 18см
диаметр в 2 раза больше окружности, значит диаметр(d)=2R=36см
