SA=4pir^2
c=2pir
so
c=30
30=2pir
divide 2
15=pir
divide by pi
15/pi=r
sub
SA=4pir^2
SA=4pi(15/pi)^2
SA=4pi(225/pi^2)
SA=900/pi squaer feet
if use pi=3.141592
SA=286.47889756541160438399077407053 square feet or about 286 square feet
Answer: 1:10,000
Step-by-step explanation:
given data:
distance of the nearest star system = 100,000,000
distance to size ration of the sun earth system = 10,000
therefore;
100,000,000 / 10,000
= 10,000
The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about 1:10,000 times that of the Sun-Earth system.
The domain of the function f(x)= is all numbers greater than or up to 2.
Given Function f(x)=
We have to search out the domain of the function f(x)=
Domain is that the value of x which we put within the function to induce the various values and range is that the value which we get after putting the worth.
f(x)=
put the function =0
squaring either side we get
x-2=0
x=2
So the domain of the function f(x)= is [2,∞) because we are able to put all values greater than 2 within the function.
Hence the domain of the function is [2,∞).

The positive linear correlation is present in the scatter plot option first “positive” is correct.
<h3>What is the line of best fit?</h3>
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
We have given a scatter plot in the picture.
As we can see in the scatter plot the dots are not so close that the correlation between x and y will be weak.
If we draw a line of best fit the slope of the line will be positive, the correlation will be positive.
Thus, the positive linear correlation is present in the scatter plot option first “positive” is correct.
