The circumference C of a circle with radius r is calculated using the formula below.
C=2π rFrom the exercise we know that the circumference of the circle is 23cm. By substituting 23 for C in the formula, we can calculate r.
We found that the radius rounded to the nearest hundredth is 3.66cm. Now, to find the diameter we can multiply the radius by 2.
2* 3.66=7.32cm
The circle's diameter rounded to the nearest hundredth is 7.32cm.
