Step-by-step explanation:

Given A circular pool of diameter 28 m has a circular path of width 7 m around it.  

  • Area of the path will be π (R^2 – r^2)
  •     So radius = d / 2 = 28 / 2 = 14
  • So R = 14 + 7 = 21 m
  • Now r = 21 – 7 = 14 m
  • Now Area of the path = π (R^2 – r^2)
  •                                       = 22 / 7 (21^2 – 14^2)
  •                                        = 22 / 7 x 245
  •                                        = 770 m^2
