Question

the numerical value of area and perimeter of a circular field is equal.the length of diagonal of square circumscribe by a circle is​

Answer 1

Answer:

Length of diagonal of square = 4

Step-by-step explanation:

Here, 2πr = π$r^{2}$                   ( Eliminate π on both sides )

Therefore, 2r =  $r^{2}$                

2r/r=r

2=r

Thus, the radius will be 2 and diameter is 4
