Question

a wire is in a circular shape of diameter 56 cm.if it is rebent into of a square find the area of square enclosed by it.which figure encloses more area circle or square and by how much./
​

Answer 1

Answer:

Diameter of circle = 56cm = Length of square

Radius =

$= \frac{diameter}{2}cm \\ = \frac{56}{2}cm \\ = 28cm$

Area of circle =

$= \pi \: r^{2} \\ = \frac{22}{7} \times 28 \times 28 \\ = 2464cm^{2}$

Area of square = side * side

= 56 * 56

= 3136cm²

Area of (Square>Circle)

Area of Square is bigger than the circle by = (3136-2464)cm²

= 672cm²
