Question

4) Знайдіть периметр n- кутника, якщо радіус вписаного у нього кола r. n=4 r=6 см

Answer 1

Ответ:
48см

Решение:
а=2*r=2*6=12см сторона квадрата;
Р=4а=4*12=48см

Answer 2

Calculating the Perimeter of an n-Sided Polygon with a Inscribed Circle

To find the perimeter of an n-sided polygon with a radius of the inscribed circle being r, we can use the formula:

Perimeter = n * 2 * r * tan(π/n)

Given: - n = 4 - r = 6 cm

Using the given values, we can calculate the perimeter using the formula.

Perimeter = 4 * 2 * 6 * tan(π/4)

Now, let's calculate the value of the perimeter.
