The area of a circle is equal to the radius squared times pie, basically:

The radius is 3, so we multiply 3 times 3 times pie to get the area.
You're gonna want to plug in the following into a calculator:

After getting 28.26 from such calculator, you need to round to the tenths place. In this number, the tenths place is the 2 next to the decimal on the right. Because the number after the 2 is a 6, that means we need to simplify the answer to (28.3). When you are rounding a number, you look at the number to the right, if it is 5 or bigger, add one and remove the rest, if it is less than 5, just get rid of the rest and leave it as it is.
Answer:
0.07
a. the distribution will be a normal distribution.
c. we would suspicious ins there is a 2 % chance of getting the required value.
Step-by-step explanation:
Let the number of times, t be = 50
Assuming that the die is fair
standard deviation = 1.71
mean = 3.5
suppose we want tp find the probability of a 2 showing. The solution becomes:
probability = 
c. the mean of rolls will be 0.07
Factor the left side:-
x (19 + r) = -37 + w
x = ( -37 + w) / (19 + r) Answer
Answer: 13%
Step-by-step explanation:
Given : A piece of luggage sells for $225.00 it is on sale this week for $195.00 .
Decrease in price = $225.00-$195.00= $30.00
Formula to find the percent decrease :-
![\dfrac{\text{Decrease in price}}{\text{Previous price}}\times100\\\\=\dfrac{30}{225}\times100=13.3333333333\approx13\%\ \ [\text{Rounded to the nearest whole percent.}]](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BDecrease%20in%20price%7D%7D%7B%5Ctext%7BPrevious%20price%7D%7D%5Ctimes100%5C%5C%5C%5C%3D%5Cdfrac%7B30%7D%7B225%7D%5Ctimes100%3D13.3333333333%5Capprox13%5C%25%5C%20%5C%20%5B%5Ctext%7BRounded%20to%20the%20nearest%20whole%20percent.%7D%5D)
Hence, the percent decrease = 13%
