Question 107164This question is from textbook Elemetary Algebra
: The length of a radius of a circle is the same as the length of a side of a square. If the circumference of the circle is 15.96 centimeters longer than the perimeter of the square, find the length of a radius of the cicle. (use 3.14 as an approximation for pi)
I know the answer is 7 centimeters but I would like to know how to set it up and solve it.
Thank you
