Answer:
2πr cm
Step-by-step explanation:
The circumference of a circle of radius r is ...
C = 2πr
For a radius of (r cm), the circumference is ...
A = 2π(r cm) = 2πr cm
For a radius of (2r cm), the circumference is ...
B = 2π(2r cm) = 4πr cm
Then the difference between the circumferences is ...
B -A = (4πr cm) -(2πr cm) = 2πr cm . . . . difference in circumference
Answer:
Step-by-step explanation:
Using:
we will have two solutions.
x^2-3x+1=0
So, a=1 b=-3 c=1
We have two solutions:
Your denominator is going to be 4 digits. "18,18,18,18".
