Hello!! 
So first you need to find the area of the green circle. The formula for finding area for a circle is A = π r2. So the area for the green circle is 28.26 cm. Then you need to find the area of the blue circle. (Using the same formula) which would be 78.5. Then you subtract the value of the green circle to get the value of the shaded region which then your final answer is 50.24 cm. Hope this helped!!

<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x + 3
<u>Step 2: Find</u>
- Swap:                                                                                                                 x = y + 3
- [Subtraction Property of Equality] Isolate <em>y</em>:                                                      x - 3 = y
- Rewrite:                                                                                                             f⁻¹(x) = x - 3
 
        
             
        
        
        
Step-by-step explanation:
The statement in the above question is True.
Sum of three prime numbers (other than  two)  is always odd.
Going by Christian Goldbach number theory ,
- Goldbach stated that every odd whole number greater than 5 can be written as sum of three prime numbers .  
  Lets take an example,
-  3 + 3 + 5 = 11
-  3 + 5 + 5 = 13
-  5 + 5 + 7 = 17
Later on in 2013  the Mathematician <u>Harald Helfgott</u> proved this theory true for all odd numbers greater than five.
 
        
             
        
        
        
Speed = distance / time
speed = 135/3 = 45 miles per hr <==
