Question

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 =$\frac{22}{7}$)

Answer 1

radius of circle =7cm

area of circle=154cm sq.

length of each side of sq.=11cm

area of sq.=121 cm sq.
