Question

Four circular cardboard pieces, each of diameter 28 cm are placed in such a way that each piece touches two other pieces. Find the area of the space enclosed by the four pieces. 

  • A) 195 cm2
  • B) 134 cm2
  • C) 168 cm2
  • D) 162 cm2
  • E) None of these
Solution

C) 168 cm2

Required area = area of square shown in figure – 4*areas of 1/4th parts of each circle, so
Required area = 28*28 – 4*(1/4)*(22/7)*14*14

C) 168 cm2

Required area = area of square shown in figure – 4*areas of 1/4th parts of each circle, so
Required area = 28*28 – 4*(1/4)*(22/7)*14*14
