Question

An earthquake was felt throughout a circular area of 1808.64 Square miles what was the radius of the circular area

A.24 miles
B. 12 miles
c. 20 miles
d. 576 miles

Answer 1

I agree 24 miles

Explanation:

the person above is correct

Answer 2

A

Explanation:

The area of a circle is given by the formula:

`A=\pi r^2`

Where A is the area and r is the radius.

Since we already know the area, we can plug it in and solve for r. Thus:

`1808.64=\pi r^2\\`

Divide both sides by π. We can use 3.14 as an approximation. The πs on the right cancel out:

`1808.64/(3.14)=r^2\\r^2=576`

Take the square root of each side:

`√(r^2)=√(576)`

The squares on the left cancel. The root of 576 is 24:

`r=24`

Therefore, the radius is 24.
