Question

If the circumference of circle is 314m then its diameter will be

Answer 1

Answer: Area is πr^2=314

r^2=314/3.14=100cm2

r=10cm

Circumference=2*3.14*10=62.8cm

Step-by-step explanation:

Answer 2

$Circumference = 314 \: m$

$314 = 2 \times 314 \times r$

$r = \frac{314}{2 \times 314}$

$r = \frac{1}{2}$

$Area \: of \: Circle = \pi \times (\frac{1}{2})^{2}$

$= \frac{\pi}{4} {m}^{2}$
