Question

a wire is bent in the shapeofa square with an areaof 121cm square if the sme wire is bent in the from of circle findthe radius of the circle
​

Answer 1

Answer:

the radius will be in decimals but answer can be written in the form of √ too

Answer 2

Answer:

$let \: the \: side \: ofsquare \: be \: x \: \\ then \: area = 121 {cm}^{2} \\ area = {x}^{2} \\121 = {x}^{2} \\ x = \sqrt{121 } \\ x = 11cm \\ perimeter \: of \: square \: = \: circumference \: of \: circle \: \\ perimeter \: of \: square \: = 4 \times side \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 4 \times 11 = 44cm \\ circumference \: of \: circle = 44cm \\ 2 \times \pi \times r = 44 \: ( \: r = \: radius \: of \: circle) \\ 2 \times \frac{22}{7} \times r = 44 \\ r = \frac{44 \times 7}{22 \times 2} \\ r = 7cm$

Step-by-step explanation:

radius of circle is 7 cm
