Question

Area of circle is 38.5sq . Cm find circmfrence

Answer 1

$\huge{\mathfrak{Answer \ :-}}$

Area of Circle = 38.5 sq. cm

$= \pi {r}^{2} = 38.5$

$= \frac{22}{7} \times {r}^{2} = 38.5$


${r}^{2} = 38.5 \times \dfrac{7}{22}$

${r}^{2} = 12.25$

r = 3.5 cm

Circumference of Circle = 2πr

$= 2 \times \dfrac{22}{7} \times 3.5$


= 22

Circumference of Circle = 22 cm.
