$\Huge\mathcal\orange{CIRCLE}$

$\Large\mathfrak\red{\implies \: area=\pi \: {r}^{2} }$

$\Large\mathfrak\red{\implies \: area= \: \pi \: (\frac{d}{2} ) ^{2} }$

$\Large\mathfrak\red{\implies \: area= \frac{ \pi \: {d}^{2} }{4} </p><p> }$

$\Large\mathfrak\pink{\implies \: circumference= 2\pi r}$

$\Large\mathfrak\purple{\implies \: semi circle = \frac{ \pi \: {r}^{2} }{2} </p><p> }$
