Question

A square with the side length of 6 units is inscribed in a circle so that all four vertices are on the circle. Find the circumference of the circle.

  1. 27 units    
  2. 32 units    
  3. 25 units    
  4. 34 units    

hintHint:

Circumference = pi cross times D

The correct answer is: 27 units


    Diagonal length of square = side length cross times square root of 2 = 6 square root of 2 = 8.48
    Circumference = pi cross times D
    = 3.14 cross times 8.48 = 26.6 …27 units
