The distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.
<h3>Circumference, diameter and radius</h3>
Since the circumference of the CD is about 37.7cm
We can determine the radius of the CD as follows;
Circumference, C = 37.7 = 2 π × r.
However, the diameter of the hole in the center is; 1.5cm, therefore, the radius of the hole in the center is; 1.5/2 = 0.75cm.
Ultimately, the distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.

Answer:
8926 bacteria
Step-by-step explanation:
We have been given that the population of a bacteria in an experiment has been increasing by 80% each day. There were 25 bacteria at the beginning of the experiment. We are asked to find the number of bacteria in 10 days.
We will use exponential growth formula to solve our given problem.
, where,
y = Final amount
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
Upon substituting our given values in above formula, we will get:
To find number of bacteria in 10 days, we will substitute in our formula as:
Therefore, there will be approximately 8926 bacteria in 10 days.
