Well hello again :3. This is also quite simple. The diameter of a circle is 2 times the radius. So we can refit this into the equation and say that our new formula using diameter is

. Now we can say that 10/2 is 5 and

is 25. Therefore your answer is

or 78.54.
The answer is C because if you do 7 divided by 25 your answer is 0.28
You should have you answer as
X = -8/3
Answer:
Well, Those best choice will be is: A. The area of a circle depends on the length of the radius.
B. The area of a sector depends on the ratio of the central angle to the entire. D. The area of the entire circle can be used to find the area of a sector. E. The area of a sector can be used to find the area of a circle. Hope This Helps!!~
The answer is $14 because 65% of $40 is 26 and 40-26=14
