Answer:

9

Step-by-step explanation:

The reason why it is 9 is because if you look to the bigger triangle, you can see that 15 is 3/4 the size of 20, so once you find what number is 3/4 of 12, you have the answer, 9! Hope this helps!

An earthquake was felt throughout a circular area of 1,808.64 square miles. What was the radius of the circular area?
spin [16.1K]

A. 24 miles

Explanation:

the area inside a circle is given by:

A=\pi r^2

where r is the radius of the circle.

In this problem, we know the circular area:

A=1,808.64 mi^2

So we can re-arrange the equation above to find r, the radius:

r=\sqrt{\frac{A}{\pi}}=\sqrt{\frac{1,808.64}{\pi}}=24.0 mi

so, the radius of the circular area is 24 miles.
