Answer:
Step-by-step explanation:
The formula for the area of a circle is 
, r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however is the exact answer.
Answer:
A
Step-by-step explanation:
Expand parentheses:
Move all y's to one side and numbers to the other:
Divide both sides by -6. Since you are dividing both sides by a negative number, you need to flip the comparator:

Answer:
Lynnette can wash 2111109 in 11 days
Step-by-step explanation:
Have a good day :)
The answer should not depend on which machine or which pencil you use to
find it. If you work a problem two different ways and get two different answers,
then at least one of them is wrong, and there's a pretty good chance that both
of them are.
(9.99 of anything) + (1.11 of the same thing) = 11.1 of them
9.99 (x 10^-2) + 1.11 (x 10^-2) = <em>11.1 (x 10^-2)</em> .
Can we do any more with that ?
10^-2 = 1 / 10^2 = 1 / 100 .
11.1 x 10^-2 = 11.1 / 100 = <em>0.111</em>
