If the circumference of a circle sheet is 154 M find its radius also find the area of sheet

Answer 1

Answer:

Step-by-step explanation:

Answer 2

$Given,\: The\:\:circumference\:\:of\:\:circle\:=2\pi r=154\:m\\\\ r\:=\frac{154}{2\pi }=\frac{154\times7}{2\times22}=\frac{7\times7}{2}=\frac{49}{2}=24.5\:m$

$Now, Area\:\:of\:\:sheet\:=\pi r^{2} =\frac{22}{7} \times (\frac{49}{2})^2\\\\\frac{22\times49\times49}{7\times2\times2} =\frac{11\times7\times49}{2} =\frac{3773}{2} =\:1886.5\:\:m^2$
