A circular hot spring has a diameter of 110 meters. Over time, the diameter

of the spring decreases by 3 meters. By how many square meters does the
area of the hot spring decrease? PLEASEE IM BEGGING ANSWER ;(

Answer 1

Explanation:

Hello!

We want to know the area of the original circle - the now circle.

The original circle's diameter is 110 meters.

To figure out the area you use this formula:
`r^2*pi`

The diameter is 107 meters, so the equation is
`55^2`
`*\pi`.

The area is about 9503.3 meters.

The next area is the "now circle".

The now circle's diameter is 107 meters.

When you use this formula, you end up with 
`53.5^2*\pi`.

The area is about 8892 meters.

So it's just basic subtraction!

I'll let you figure out the rest.
