One circle has a circumference half as large as that of a

Answer 1

Answer:

The ratio that compares the diameter of the first circle to the diameter of the second circle is $\frac{1}{2}$

Step-by-step explanation:

Circumference of a circle:

The circumference of a circle of diameter d is given by:

$C = \pi d$

In which d is the diameter.

One circle has a circumference half as large as that of a second circle.

We have that:

$C_1 = \frac{C_2}{2}$

So

$\pi d_1 = \frac{\pi d_2}{2}$

Simplifying by $\pi$

$d_1 = \frac{d_2}{2}$

$\frac{d_1}{d_2} = \frac{1}{2}$

The ratio that compares the diameter of the first circle to the diameter of the second circle is $\frac{1}{2}$
