The area of a circle with radius r is πr². So you need to find r such that
πr² = 56π
⇒ r² = 56
⇒ r = √56 = 2√14

Step-by-step explanation:
Exponential function:
An exponential function has the following format:

In which y(0) is the initial value and r is the rate of change, as a decimal. If r is positive, it is a increase. If it is negative, it is a decrease.
In this question:
We have that:

So


So a decrease of 63.5%.
