Question

Люди помогите пожалуйста, Длина окружности радиусом R равна C. Заполните таблицу R= C= 2; -; 5; -; -; 4п; 2/7п; -; -; 27; √3; -; -. 6,25.

Answer 1

$C=2\pi R\ ;R=\frac{C}{2\pi}\\C_1=2\pi*2=4\pi\\C_2=2\pi*5=10\pi\\R_3=\frac{4\pi}{2\pi}=2\\C_4=2\pi*\frac{2}{7}\pi=\frac{4\pi^2}{7}\\R_5=\frac{27}{2\pi}=13,5\pi\\C_6=2\pi*\sqrt3=2\sqrt3\pi\\R_7=\frac{2\pi}{6,25}=0,32\pi$

Answer 2

The Relationship Between the Radius and Circumference of a Circle

The circumference of a circle is the distance around its outer edge, while the radius is the distance from the center of the circle to any point on its edge. There is a mathematical relationship between the radius and the circumference of a circle.

The formula to calculate the circumference of a circle is:

C = 2πR

Where: - C is the circumference of the circle - R is the radius of the circle - π (pi) is a mathematical constant approximately equal to 3.14159

Using this formula, we can calculate the circumference of a circle for different values of the radius.

Table of Radius and Circumference Values

| R | C | |---|---| | 2 | 2π(2) = 4π ≈ 12.57 | | 5 | 2π(5) = 10π ≈ 31.42 | | 27 | 2π(27) = 54π ≈ 169.65 | | √3 | 2π(√3) ≈ 2π(1.732) ≈ 3.464π ≈ 10.88 | | 6.25 | 2π(6.25) ≈ 12.5π ≈ 39.27 |

Please note that the values in the table are approximate, as π is an irrational number and cannot be expressed exactly as a finite decimal. The values provided are rounded to two decimal places for simplicity.

I hope this helps! Let me know if you have any further questions.
