Can someone please help me solve the problem

Given:

The exponential function is:

To find:

The percentage rate of increase or decrease.

Solution:

The general exponential function is:

          ...(i)

Where, a is the initial value, |r| is the growth rate in decimals if r>0 and |r| is the decay rate in decimal if r<0.

The exponential function is:

It can be written as:

       ...(ii)

On comparing (i) and (ii), we get

Since r is negative, therefore the given function is a decreasing or decay function.

Now,

So, the rate of decrease is 0.06. Multiply this number by 100 to get the percentage.

Therefore, the rate of decrease is 6%.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
