The solution would be B) (18,-20)
Answer: Therefore, the geometric mean of 8 and 18 is 12. Therefore, the geometric mean of 8 and 18 is 12.
Step-by-step explanation:
Answer:
r = 8 ft
Step-by-step explanation:
The formula for circumference of a circle is
C = 2 * pi *r
We know the circumference is 16 pi
16 pi = 2 pi r
Divide each side by 2pi
16 pi /2 pi = 2 pi r / (2pi)
8 = r
