Help me find the area of this circle

ch4aika [34]

The area would be approximately 153.94.

The area of a circle is pie multiplied by r^2.

So you have the radius, which is r. Plug in r. Technically you have two numbers because pie equals approximately 3.14.

forsale [732]

Answer:

B) μD = 0.60 ± 0.10(1.397)

Step-by-step explanation:

The confidence interval is given by:

$MD±t_{\alpha/2, n-1} \frac{s}{\sqrt{n} }$

Where

MD=60

n=9

df=n-1=8

$t_{\alpha/2, n-1}=1.397$

$s=\sqrt{0.09} =0.3$

Then the confidence interval is

μD=0.60±1.397*(0.3/√9)

μD=0.60±0.10*(1.397)

At the grocery store, Lindsay bought several pounds of strawberries. The strawberries cost $2.25 per pound. After she paid the c

yanalaym [24]

Let x equal the number of strawberries while y is the total amount of money she had.

The equation is: 2.25(x)+8.75=y.

Then, if she bought 4 pounds of strawberries, it would work as follows: 2.25(4)+8.75 is the total amount. That means 9+8.75 would be the total. Thus, the amount of money she started out with was 17.75 dollars.
