Question

Длина окружности 15,7 см найдите ее диаметр, округлив число П до сотых

Answer 1

L=П* D, D ДИАМЕТР,
L=15.7(подставляем)
15,7=ПD
D=15.7/П, П=3,14
D=15.7/3.14=5 
ответ: 5 см

Answer 2

Calculation of Diameter from Circumference

To find the diameter of a circle when the circumference is given, we can use the formula:

Circumference = π * Diameter

Given that the circumference is 15.7 cm, we can substitute this value into the formula and solve for the diameter.

15.7 cm = π * Diameter

To find the diameter, we need to divide both sides of the equation by π:

Diameter = 15.7 cm / π

Now, let's calculate the value of the diameter, rounding π to the hundredths place.

Diameter = 15.7 cm / 3.14

Calculating this, we get:

Diameter ≈ 5 cm

Therefore, the diameter of the circle is approximately 5 cm.
