Answer:

$A=6.33\ cm^2$

Explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=(28)/(3.14)\ cm$

$\pi=3.14$

substitute the values

(28)/(3.14)=2(3.14)r

$r=(28)/(19.7192)\ cm$

$r=1.42\ cm$

step 2

Find the area of the circle

The area of the circle is equal to

$A=\pi r^(2)$

substitute the values

A=(3.14)(1.42)^(2)

$A=6.33\ cm^2$
