Question

1. Find the diameter of the circle whose circumfrence is 121



​

Answer 1

$\bf{Diameter = \frac{circumference}{\pi} }$

$= > \frac{121}{3.14} = 38.53$

So diameter in given circle is 38.53

Answer 2

$\huge \underline{ \underline{ \bf \purple{Solution :}}}$

$\implies \sf Circumference =2\pi r \\ \\\implies \sf 121 = 2 \times \frac{22}{7} \times r \\ \\\implies \sf r = \frac{121 \times 7}{44} \\ \\\implies \sf r = 19.25$

_______________________

$\implies \sf Diameter = 2r \\ \\ \implies \sf Diameter = 2 \times 19.25 \\ \\ \implies \sf Diameter = 38.50$
