Question

solve this plzzzz fast

Answer 1

sides of square is 16.5 cm
perimeter is 4s
》4 (16.5)=66 cm
Then it is turned into a circle
》2piR=2 (22/7)(R)=66 cm
》2R=(66×7)/22
》2R=3×7
》R=21/2
radius of the circle is 21/2 cm

Answer 2

the perimeters of square is =perimeter of circle.
perimeter of square is 66cm = perimeter of circle.
cicumference of circle =66cm.
=2 ×pie ×r =66cm.
so radius is 10.5cm.
