Question

how much is the radius of a circular wire covering the area of 44 cm square.​

Answer 1

Answer:

length of wire=44cm. circumference of circle=>2πr where r is the radius of circle. Now the wire is bent into a square...perimeter of square=4s.

Answer 2

Answer:

$area \: of \: circle = a = \pi {r}^{2} \: \: \: \: \: \: \: \: \: < r = radius >$

$a = 44 = \frac{22}{7} \times {r}^{2}$

$a = 2 = \frac{1}{7} \times {r}^{2}$

$a = 14 = {r}^{2}$

$r = \sqrt{14}$

$r = 3.741$
