Question

Find the exact area of a circle is the circumference is 58 π

Answer 1

2640.74

Explanation:

Circumference : π * 2r

Area of circle : π *
`r^(2)`

For this particular circumference,

Circumference : π * 58

58 = 2r

So by dividing we learn that,

r = 29

When we substitute the radius into the equation for area, we get,

Area of circle : π *
`29^(2)`

Area of circle : π * 841

Area of circle : 2640.74

* I used 3.14 as π
