Answer 1

1) 1,2×2=2,4 2) 2,4×3,14=7,536 P.S: 3,14- число ПИ

Answer 2

Calculating the Length of a Circle

To find the length of a circle, also known as the circumference, the formula is used: circumference = π * diameter.

Given that the circumference of the first circle is 1.2m, we can calculate the diameter of the first circle using the formula: diameter = circumference / π.

Let's calculate the diameter of the first circle: ``` diameter_first_circle = 1.2 / π ```

Now, we are asked to find the length of another circle whose diameter is 2 times the diameter of the first circle.

Calculating the Diameter of the Second Circle

The diameter of the second circle is 2 times the diameter of the first circle, so: ``` diameter_second_circle = 2 * diameter_first_circle ```

Calculating the Circumference of the Second Circle

Now that we have the diameter of the second circle, we can calculate its circumference using the formula: ``` circumference_second_circle = π * diameter_second_circle ```

Let's calculate the circumference of the second circle using the value of π as approximately 3.14159.

The length of the second circle's circumference is approximately equal to the calculated value.
