Answer: 593.46 mm²
<u>Step-by-step explanation:</u>
The diameter of the big circle is 2(7) + 20 = 34
divide the diameter by 2 to get the radius (r) = 17
Area = π·r²
= π(17)²
= 289 π
The diameter of the big circle is 20
divide the diameter by 2 to get the radius (r) = 10
Area = π·r²
= π(10)²
= 100 π
The area of the shaded region is the difference between the area of the big circle and the area of the small circle.
= 289 π - 100 π
= 189 π
= 189(3.14)
= 593.46

This will be an exponential function. To find the growth rate, we can write out the terms of the sequence that goes along with it: 10, 20, 40, ...
"Growth rate" is the same as percent of increase or decrease. We find the amount of increase and divide by the original amount: 20-10 = 10 increase; 10/10 = 1.
The exponential function is of the form
f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods. Using the variables given to us in the problem along with this information, we have:
Divide both sides by 10:
We will use logarithms to solve this:
