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
Angle F is equal to angle G so 5x + 18 = 7x-12 so you would solve for x which would equal 15
Answer: one value
Step-by-step explanation:
8 - x = 9
collecting the like terms
x = 8 - 9
x = -1
0, because 1/2 = 0.50. therefore .07 is more closer to 0
