Question

A wire is bent in the form of of a square of area 1936cmSquare. If the same wire is bent to form a circle. Find the radius of the circle and the area enclosed.​

Answer 1

Answer:

area of square whose side is 'a' = 1936 (given)

ie

Step-by-step explanation:

$\\ {a}^{2} = 1936 \\ a = \sqrt{1936} \\ a = 44$

now circumstances of square is

$4 \times a$

ie circumstances of square is 176 = circumstances of circle

thus

$2\pi \times r \: = 176 \: m \\ thus \: r = 176 \div 2\pi \\ r = 28 \: m\\ area \: of \: circle \: is \: \pi \times {r}^{2} \: = 4312 \: m$
