Answer 1

Answer:

total length of wire = 66 cm

circumference of circle = 2πr

66=2×22/7×r

10.5 = r

Answer 2

Answer:

10.5 cm

Explanation:

Given :

Side of square = 16.5 cm

π = 22/7

Procedure :

The length of the wire = perimeter of the square since it is bent in the form of square.

Formula : Perimeter of a square = (4 × s) units

Hence, perimeter of the square = 4 × 16.5 cm

=> P = 2 × 33 cm

Hence perimeter of the square = 66 cm.

Hence length of the wire = 66 cm.

Now it is bent into a circle.

Hence the perimeter of the circle = Length of the wire.

Formula : Perimeter of a circle = (2πr) units

Hence, the perimeter of the circle = 66 cm.

=> 2 × π × r = 66

=> (44/7) × r = 66

=> (22/7) × r = 33

=> r = 21/2 cm

=> r = 10.5 cm

Hence the radius of the circle = 10.5 cm.
