$\huge{\orange{\fbox{\fbox{\blue{\bigstar{\mathfrak{\red{Answer}}}}}}}}$

$<marquee scrollamount = 700>✌️✌️✌️</marquee>$ $<marquee scrollamount = 500>⭐⭐⭐</marquee>$

Area of Circle = $\pi×r^2$

=> $156 = \frac{22}{7}×r^2$

=> $\frac{156×7}{22}=r^2$

=> $\frac{1092}{22}=r^2$

=> $\sqrt{49.6363..}=r$

=> $\large{\blue{7.04}}=r$

Circumference of circle= $2×\pi×r$

=> $2×\frac{22}{7}×7.04$

=> $\huge\orange{\fbox{\pink{44.2514}}}$
