The answer is 180°. Hope this helps!
You are changing the sign on one so to keep an equilibrium you change the other sign too
Answer:
no lol
Step-by-step explanation:
Part A:
Circumference = πd
Circle A: d = 7
7π = 21.98
π = 21.98/7 = 3.14
Circle B: d = 6
6π = 18.84
π = 3.14
Part B:
Area = πr^2
Circle A: r = 3.5
π3.5^2 = 38.465
12.25π = 38.465
π = 3.14
Circle B: r = 3
π3^2 = 28.26
9π = 28.26
π = 3.14
Part C: The value of π is the same in circles A and B
First divide 228 miles by 6 hours and u get 38 miles per hour
next, divide 285 miles by 38 miles and u get 15/2 or 7.5 hours
the answer is 7 and a half hours
hope this helps! good luck!
