The circumference is 1.2 m. What is the circumference of a circle that has 2 times the diameter of the first circle?

We know that the circumference can be found based on the formula:

l = 2πr = πd

Where
l – circumference
r – radius of the circle
d – circle diameter
π = 3.14 constant

We know that the circumference is 1.2 meters, then its diameter will be:

l = πd
d = l / π = 1.2 / 3.14 = 0.38 meters

Now we will find the circumference of a circle whose diameter is twice as large as that of the original one.
The diameter of the resulting circle is:

d2 = 2 * d = 2 * 0.38 = 0.76 meters.

Now let’s find the length of the resulting circle:

l2 = πd2 = 0.76 * 3.14 = 2.4 meters
