I am not sure what the answer is but covert them into a decimal and then divide it
Answer:
Given the statement: Crater Lake in Oregon in shaped like a circle with a diameter of about 5.5 miles.
Area of circle is given by:

where
A represents the area of a circle
d represents the diameter of a circle.
then;

Substitute the given values, we have;
Area of a circle = 
=
square miles
therefore, the area of a surface of a crater lake is, 23.74625 square miles.

Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided. The expression that was provided is
.
The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common. We can see that both
and
have the number 5 and the variable c associated with them so we can factor out those two.
<u>Factor out 5c</u>
Now we have completely factored out the expression that was provided in the problem statement and we came to final answer of
.
