Chapter 1.2, Problem 72E

The circumference C of a circle is a function of its radius given by C(r)=2r. Express the radius of a circle as a function of its circumference. Call this function r(C) , Find r(36) and interpret its meaning,

Could you solve the questions with R, please? (Only R please) I took a screenshot of the data. (please write the codes based on the screenshot data) There are a total of 409 rows in the data. When you write the R codes, could you also include explanations as well? For each of X1, X2, X3, X4, 1. Plot a line plot 2. Plot the acf (autocorrelation function) 3.
