Answer:

  • given that: x²+y²=4, x²+(y-1)²=4
  • so radius of first circle is R=2 and
  • radius of second circle is r=2
  • distance between their center d=1
  • we know that angle between two circle is equal to
  • cosФ=|(R²+r²-d²)/2rR|
  • by putting values
  • cosФ=|(4+4-1)/2(2)(2)|
  • cosФ=|7/8|
  • Ф=28.96°
  • so angle between circle is 28.96°.
