Draw a circle with a radius of 3 cm. Draw another circle with a radius 2/3 of the radius of the first circle. Calculate the length of each of these circles (n = 3.14).

Let’s start by calculating the length of the first circle with a radius of 3 cm.Let’s remember the formula for calculating the circumference:

C = 2 * pi * R.

We were asked to take the values of pi equal to 3.14. We substitute the values into the formula and perform the calculations:

C1 = 2 * 3.14 * 3 = 6 * 3.14 = 18.84 cm circumference with a radius of 3 cm.

To find the length of the second circle, we first need to find its radius:

It is known to be equal to 2/3 of the radius of the first circle.

2/3 * 3 = 2 cm.

We are looking for the circumference:

C2 = 2 * 3.14 * 2 = 4 * 3.14 = 12.56 cm.
