Question

Дано r=4найти C=? S=?​

Answer 1

Ответ:

С = 8π (ед)

S = 16π(ед²)

Пошаговое объяснение:

r  = 4 - радиус

С  - длина  окружности

S - площадь окружности

Длина окружности вычисляется формулой

$C = 2\pi r = 4 \cdot 2 \pi = 8\pi$ (ед)

А площадь

$S = \pi r ^2 = 4^2 \cdot \pi = 16\pi$ (ед²)

Answer 2

Ответ:

25,12 см; 50,24 см²

Пошаговое объяснение:

R = 4 см

π = 3,14

С = ? см

S = ? см²

С = 2πR

С = 2 * 3,14 * 4 = 25,12 см

S = πR²

S = 3,14 * 4² = 3,14 * 16 = 50,24 см²

Answer 3

Calculating C and S for a Given Value of r

To calculate the values of C and S for a given value of r, we need to understand the context in which these variables are used. Unfortunately, the search results provided do not contain specific information about the variables C and S in relation to the given value of r. As a result, I'm unable to provide a direct answer based on the search results provided.

If you could provide more context or specific information about the variables C and S and their relationship to the value of r, I would be happy to help you with the calculations.
