Find the circumference of the circle with 1/4 Pi square centimetre square 2<br>​
otez555 [7]

Answer:

The circumference of the circle is 6 cm (approximately).

Step-by-step explanation:

Given:

Area of the circle = 1/4π²

Now, to get the circumference of the circle we need the radius.

So, finding the radius by putting the formula of area:

Area = \pi r^{2}

\frac{1}{4} \pi ^{2} = \pi r^{2}

dividing π by both sides:

\frac{1}{4}\pi=r^{2}

using square root on both the sides:

\frac{1}{2}\sqrt{\pi } = r

So, the radius is \frac{1}{2}\sqrt{\pi }

Now, putting the formula of circumference:

circumference=2\pi r

                              =2\pi\frac{1}{2} \sqrt{\pi}

                              =\pi \sqrt{\pi}

putting the value of π =3.14

                              =3.14\times\sqrt{3.14}

                              =3.14\times1.77

                              =5.56

Circumference = 5.56 cm

Therefore, the circumference of the circle is 6 cm (approximately).
