Answer 1

Answer:

pls mark me as brainliest

Step-by-step explanation:

side of square =22cm

perimeter of square =88cm

length of wire =88cm

circumference of circle=88cm

2pie r =88

pie r= 44

r=44×7/22

r=14cm

Answer 2

Answer:

Step-by-step explanation:

Given, side of a square is 22cm The wire has same length.  

Hence, perimeter of square arid circumference of circle are equal.  

ACQ,  

Circumference of circle = Perimeter of square  

=2×π×r=4×(side)

⇒2×  

7

22

​  

×r=4×22

⇒r=  

2×22

4×22×7

​  

 

⇒r=17cm

Therefore, 14cm is the radius of the circle.
