Question

Б) Найдите радиус окружности , если нё диаметр равен : 6 см, 9 см , 12 м .срочно !!! пожалуйста!! !!!

Answer 1

Радиус = диаметр:2
6:2=3
9:2=4,5
12:2=6

Answer 2

Finding the Radius of a Circle

To find the radius of a circle, we can use the formula:

C = 2πR

Where: - C is the circumference of the circle - R is the radius of the circle - π is a mathematical constant approximately equal to 3.14

Let's calculate the radius for each given diameter:

1. Diameter = 6 cm: - Circumference (C) = 2πR - Diameter (D) = 6 cm - We know that D = 2R, so R = D/2 = 6/2 = 3 cm

2. Diameter = 9 cm: - Circumference (C) = 2πR - Diameter (D) = 9 cm - We know that D = 2R, so R = D/2 = 9/2 = 4.5 cm

3. Diameter = 12 m: - Circumference (C) = 2πR - Diameter (D) = 12 m - We know that D = 2R, so R = D/2 = 12/2 = 6 m

Therefore, the radius of the circle is: - For a diameter of 6 cm, the radius is 3 cm. - For a diameter of 9 cm, the radius is 4.5 cm. - For a diameter of 12 m, the radius is 6 m.

Please note that the calculations are based on the formula for the circumference of a circle and the relationship between the diameter and radius.
