  1. Question⇒ A steel wire when bent in the form of a square encloses an area of 196 sq . cm . if the same wire is bent into the form of a circle, find the area of the circle. (use pi = 22/7 )

Step-by-step explanation:

  • Perimeter of square = perimeter of circle

  • A of sq = 196
  • a²=196
  • a=√196
  • a=14

  • p of sq = 4a = 4(14) = 56
  • Perimeter of square = perimeter of circle
  • 56 = 2πr
  • r = 98/11

  • A of cr = πr²
  • =22/7 * 98/11 * 98/11
  • =124.72 sq units.

Answer:

Step-by-step explanation:

area=196

side^2=196

side=14

perimeter=4*14=56

when it is bent down to circle the perimeter is same

circle perimeter=square perimeter=56

2pie r=56

r(radius)=56/2pie          we know pie=22/7

r=56/2*22/7

r=56*7/44

r=8.90cm

therefore area=pie*r^2

=22/7*79.21

=249cm^2

approx
