Area = r^2 x PI
to find r take the square root of the area:
r = √100 = 10
The circumference of a circle is the diameter times PI.
The diameter is 2 times r = 2 x 10 = 20
The circumference = 20PI m
The answer is C.

Answer:
<em>y = $ x/3 </em>
Step-by-step explanation:
Let the amount of dollars in Teo's bank on Tuesday be $x and the amount in his bank on Friday be $y.
If the number of dollars in Teo's bank account on Tuesday was 3 times as
much as the amount on Friday, this can be represented mathematically as;
x = 3y where y is the amount in his bank on Friday.
The amount of dollars in his account on friday will be gotten by dividing both sides of the equation by 3
3y = x
3y/3 = x/3
y = x/3
<em>Hence the amount of dollars in his account on Friday is y = $ x/3 </em>
