An apple pie with a circumference of 28.26 inches is cut into 6 equal-sized pieces. Two pieces of the pie are eaten. What is the area of the pie that is left? Select the correct answer. Use 3.14 for π.

• choixongdong: C = πd
  d = C / π
  d = 28.26 / 3.14
  d = 9 in
  
  but r = d/2 = 9/2 = 4.5 in
  
  A = π r^2
  = 3.14 x (4.5^2)
  = 3.14 x 20.25
  = 63.585
  
  divided into 6 equal
  so 63.585 / 6 = 10.5975
  
  but ate 2, so there are 4 pieces left
  4 x 10.5975 = 42.39
  
  answer
  the area of the pie that is left is 42.36 in^2
  
• Maggiegirl: hey user!!
  
  your answer is here...
  
  we know that circumference of circle = πd
  
  given the circumference of the apple pie = 28.26 in.
  
  therefore πd = 28.26 in.
  
  ==> 3.14 × d = 28.26 in.
  
  ==> d = 28.26/3.14
  
  ==> d = 9 in.
  
  the diameter of the apple pie is 9 in.
  
  therefore radius of the apple pie = 9/2 = 4.5 in.
  
  area of the apple pie = πr²
  
  == 3.14 × 4.5 × 4.5
  
  = 63.585 in²
  
  it's divided into 6 equal parts and two pieces are eaten. so the area of leftover pie = 63.585/6 × 4
  
  = 63.585/3 × 2
  
  = 21.195 × 2
  
  = 42.39 in²
  
  cheers!!
