Four circles are drawn from the corners of a square of area 49 cm2 . Find the area of 4 circles outside the square

• diameter of circle=7
  radius=3.5cms
  area of 4 circles=4(3.14159*3.5*3.5)=154
  area of 4 circles outside the square=area of 4 circles-area of 1 circle=154-38.5=115.5

• r=3.5
  area of a circle outside the square=3/4* area of a circle=3/4*pi*(3.5)^2=3/4*(22/7)*(7/2)^2=3/4*22*7/4
  required area= 4*3/4*22*7/4=66*7/4=33*7/2=115.5cm2

• x=7cm
  so radius-3.5cm
  area of 4 circle=3.14*3.5*3.5=154cm^2
  area of 4 circle otside square=area of 4 circle-area of square
  =154-49
  =105cm^2

• area of square=a^2=49
  a=7
  perimeter of square=4a=4(7)=28
  circumference of circle=2*pi*a=28
  a=14/pi
  area of one square=3.14*(14/pi)^2=62.3 approximately
  area of 4 circles=4(62.3)=249.2 cm2
