Question

If the circumference of the circle is 540 cm. Then find its area​

Answer 1

Answer:

Area =23,233.7612$cm^{2}$

Step-by-step explanation:

According to the information provided in the question it is given as

Circumference of circle =450 cm

We need to find the area of circle

Form the circumference of circle we can finding the radius of circle and after that from radius we find the area of circle

Circumference of circle=2$\pi$r

$C=2\pi r\\C=2\times \frac{22}{7} \times r$

$540=2\times \frac{22}{7} r$

Converting the lowest term we get

$540=2\times 3.142\times r$

$540=6.284 r$

$r=\frac{540}{6.28}$

$r=85.98$$cm$

Now

Area of circle=$\pi r^{2}$

Putting the value

$A=\frac{22}{7} \times$$85.98\times 85.98$

$A=23,233.7612cm^{2}$
