R = 8 см

D = 2R

D = 2 · 8 = 16 см

C = 2πR

C = 2·3,14·8 = 50,24 см

(или так: С = 2π · 8 = 16π)

S = πR²

S = 3,14 · 8² = 3,14 · 64 = 200,96 см²

(или так: S = π · 8² = π · 64 = 64π)


loonyawagony: топ,спасибо
SunnyStorm: Пожалуйста =)
SunnyStorm: Удачи!

Пошаговое объяснение:

D=2R=2*8=16см.

Длина круга:  3,14*16=50,24 см.

S=3,14*8²=3,14*64=200,96см²
