Длина окружности)))))))))))))))

Answer 2

To solve this problem, we need to find the circumference (C) of a circle when the diameter (D) is given as 7.3 cm.

The formula to calculate the circumference of a circle is: C = π * D

Where: C is the circumference D is the diameter π (pi) is a constant approximately equal to 3.14159

Now, plug in the given diameter (D = 7.3 cm) into the formula:

C = π * 7.3 cm

To get the value of C, you'll need to use the value of π. Since π is an irrational number (it has an infinite number of decimal places), we'll use an approximation, usually taken as 3.14.

C ≈ 3.14 * 7.3 cm

Now, calculate the value:

C ≈ 22.922 cm

So, the approximate circumference of the circle is 22.922 cm.
