Question

Consider a circle that has a circumference of 28/3.14 centimeters. What is the area of this circle? Answer fast plz also can you show work???

Answer 1

`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`
