Answer:
Circumference = 74.2924 inches.
Step-by-step explanation:
Given : area = 437.4 in².
To find : Find the circumference .
Solution : We have given area = 437.4 in².
Area = π (radius)².
π (radius)² = 437.4 in².
3.14 (radius)² = 437.4 in².
On dividing both sides by 3.14
(Radius)² = .
(Radius)² = 139.299.
On taking square root both sides
Radius = 11. 83 inches
Circumference = 2 * π * radius .
Plug the values
Circumference = 2 * 3.14 * 11.83 .
Circumference = 74.2924 inches.
Therefore, Circumference = 74.2924 inches.

<h2>Linear regression:</h2>
It is a linear model, e.g. a model that assumes a linear relationship between the input variables (x) and the single output variable (y)
The Linear regression equation for the transformed data:
We transform the predictor (x) values only. We transform the response (y) values only. We transform both the predictor (x) values and response (y) values.

Sum of X = 15
Sum of Y = 8.323
Mean X = 3
Mean Y = 1.6646
Sum of squares (SSX) = 10
Sum of products (SP) = 3.258
Regression Equation = ŷ = bX + a
b = SP/SSX = 3.26/10 = 0.3258
a = MY - bMX = 1.66 - (0.33*3) = 0.6872
ŷ = 0.3258X + 0.6872
