<u>Answer</u>
A. c = 4
<u>Explanation</u>
In algebra, what you do to one side of the equation, the same has to be done on the other side.
32c = 128
divide both sides by 32
32c = 128.
32c ÷ 32 = 128 ÷ 32
c = 128/32
= 4

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
