Question

Which statement explains why all circles are similar? All circles have 360 degrees. The diameter of every circle is proportional to the radius. The inscribed angle in every circle is proportional to the central angle. All circles have the same ratio of circumference to diameter.

Answer 1

All circles have the same ratio of circumference to diameter.

Answer 2

Answer:

All circles have the same ratio of circumference to diameter.

Step-by-step explanation:

All circles have the same ratio of the circumference to the diameter. In other words, the ratio is expressed as:

$\frac{C}{d} = constant$

During the experiments carried out, Pythagoras adopted the ratio is expressed as a constant known as pi.

This was given as:

$\pi = \frac{C}{d}$

The ratio C/d is constant regardless of the circle's size.
