Answer 2

To Find :-

• Diameter of circle

⠀ ━━━━━━━━━━━━━━━━━━━⠀⠀⠀

Given :-

• Circumference of circle = 3.3 m

Let the diameter of the circle to be 'd' m.

$\bigstar\;\boxed{\sf{\pink{Circumference_{\:(circle)} = 2 \pi r }}}$

⠀

$\rm : \; \implies 2 \pi r = 3.3 \; \; m$

$\rm : \; \implies 2 \times \dfrac{22}{7} \times r = 3.3 \; \; m$

$\rm : \; \implies D \times \dfrac{22}{7} = 3.3 \; \; m$

$\rm : \; \implies D = \dfrac{3.3 \times 7}{22} \; \; m$

$\rm : \; \implies D = \dfrac{23.1}{22} \; \; m$

$\implies{\underline{\boxed{\frak{\purple{D = 1.05\; m}}}}}\;\bigstar$

⠀

$\therefore{\underline{\sf{Hence,\; diameter\; of \; the \: circle\; is\; \bf{ 1.05\;m}.}}}$
