radius = 2pi, so diameter = 4pi
circle diameter is the length of the side of the square.
perimeter = 4*4pi = 16pi
a square in a circle with a radius of 2 pi .What is the perimeter of the square?

Isn't the diagonal of the square the same as the diameter of the circle?

So the diagonal of the square is 4π
let each side of square be x
x^2 + x^2 = 16π^2
2x^2 = 16π^2
x^2 = 8π^2
x = π√8
4x = 4π√8
= 8√2 π
let each side of square be x
x^2 + x^2 = 16π^2
2x^2 = 16π^2
x^2 = 8π^2
x = π√8
4x = 4π√8
= 8√2 π
Ms Sue, you are correct. Nice save for you and Reiny.
