# Shazli took a wire of length 44 cm and bent it into the shape of a circle. Find the radius of that circle. Also, find its area. If the same wire is bent into the shape of a square, what will be the length of each of its sides? Which figure encloses more area, the circle or the square? (Take π =22/7)

**Solution:**

Length of the wire = 44 cm

The circumference of the circle is 44 cm.

C = 2πr

44 cm = 2πr

44 = 2 × 22/7 × r

r = 44 cm × 7/44

r = 7 cm

= 22/7 × 7 cm × 7 cm

= 154 cm^{2}

Now, the wire is bent into a square.

Perimeter of square = 44 cm

4 × Side = 44 cm

Side = 44 cm / 4 = 11 cm

Area of square = Side × Side

= 11 cm × 11 cm

= 121 cm^{2}

Thus, the circle encloses more area than square.
