Answer 1

Answer:

answer for the given problem is given

Answer 2

Answer:

diagonal of a square =a√2

where a is the side of a square

Step-by-step explanation:

11=a√2

11/√2=a

area of the square=a×a

=11/√2×11/√2

=121/2

now, the area of the square =the area of the circle

area of the circle =121/2

pi×r×r=121/2

r×r=121/2 ×7/22 ( taking value of pi =22/7 )

r=11/2√7/11

diameter =2×r

=2×11/2√7/11

=11√7/11 .... ans
