Question

Area of the circle is 38.5 cm2. Its
circumference is​

Answer 1

Answer:

22cm

Step-by-step explanation:

Area of Circle= 38.5 cm²

πr²= 38.5

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

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

${r}^{2} = 1.75 \times 7 \\ {r}^{2} = 12.25 \\ r = \sqrt{12.25}$

r= 3.5 cm

Perimeter of Circle= 2πr= 2×22/7×3.5= 2×22×0.5= 22

Perimeter of Circle= 22cm
