Answer:
a 12.56 cm2
Step-by-step explanation:
area = πr² or I'd
step 1: substitute (plug in) for r which in here is 2
π(2)²
step 2: follow order of operations
(2)²= 4 *π= 12.56
P- parenthesis
E-exponent
MD- multiply and divide from left to right
AS- add and subtract from left to right
It must be true that a implies c, because of the transitive property.
If a is true, then b is true as well. But every time b is true, c is true as well.
So, "jumping" over b, we have that if a is true, c is true as well.
Think of this example:
- a: I live in Rome
- b: I live in Italy
- c: I live in Europe
It is true that 
, because Rome is inside Italy, and similarly 
, because Italy is a European state.
So, if I live in Rome, I must live in Europe as well.
