$\bold \red \star \: \large \underline{Solution:-}$

$The \: circumference \: of \: a \: circle = \red{ 2 \pi r}$

$2 \pi \pink{r} = 25. - - - ( \blue{Given:-}) \\ \\ \longrightarrow r = \frac{25}{2 \pi} . \\ \\ \longrightarrow r = \frac{25 \times 7}{2 \times 22} . \\ \\ \longrightarrow r = \frac{175}{44} . \\ \\ \longrightarrow r = \pink{3.977(approx.)}$

$\longrightarrow \bold{\pink{r = 4 \: Cm.}}$
