When the radius is 8, the area would be 201.06
Area of circle = pi x radius² (pi x 8²)
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Answer: 12
Step-by-step explanation:
The formula to find the sample size is given by:-
, where 
is the population standard deviation, 
is the z-value for the 
confidence interval and E is the margin of error .
As per given , we have
Population standard deviation : 
z-value for 95% confidence interval : 
Margin of error : E= 3
Then, the required minimum sample :-
Hence, the required minimum sample size = 12
Answer:
-5x + 8x - 4 = 3x - 4
-5y + 3 - 6y + 2y + 4 = -9y + 7
6 + x - 5 + 2x + 8 = 3x + 9
3b - b + 7 + 4b = 6b + 7
