Question

A wire in the shape of a circle encloses the area 38.5 cm². If the wire is rebent to form a square, find the
area of the
square.​

Answer 1

Answer:

1,482.25

Step by step Explanation:

A of square = S x S

= 38.5 cm x 38.5

= 1,482.25

Answer 2

Answer:

30.25 sq.cm

Step-by-step explanation:

area of circle= 38.5 sq.cm

πr^2=38.5  

r=3.5 cm

circumference= 2πr

= 2*(22/7)*3.5

= 22 cm

= length of wire

now in case of square,  

length of wire= perimeter= 22cm

side of square = 22/4 = 5.5

area of square = side^2

= 5.5^2

= 30.25 sq.cm
