z=
where
- x is the hours student work in a week, which is 10,
- M is the mean studying hour of the class, which is 9.92,

Step-by-step explanation:
Hello!
<u>The formula for finding circumference of a circle is 2πr:</u>
In that case, we can just substitute 6 meters for our radius.
6 × 2π = 12π
12 × 3.14 (about π) = 37.68
That's about 37.7 (when rounded.)
Thusly, the closest option is
.
<u>The formula for finding the area of a circle is πr²:</u>
In that case, we can just substitute 6 meters for our radius. (again.)
6² = 36
36 × π = 36π
Therefore,
is our answer.

$143
First you would have to find out the price that the tent was bumped up to.
52*150%=78
You then add the answer to your original price.
52+78=130
You then have to find the sales tax. You do this by multiplying 10% to your new price.
130*10%=13
You then have to add the sales tax to your number.
130+13=143
$143 is your answer.
