HELP PLEASE ASAP!!!!

Answer:

I may be wrong, but I learned that the first slot would be "terms". 4:3 would be an example of a ratio so it couldn't be ratio and a difference is subtracting.

The second slot would not be a geometric sequence because it is not correctly placed on the number line.

Therefore, the answers would be "terms" and "is not"

beks73 [17]

Answer:

r = 8 units

Step-by-step explanation:

The circumference is calculated using $C = 2\pi r$ . Substitute C = 50.24 units. Solve for the radius.

$C = 2 \pi r\\50.24 = 2 \pi r\\25.12 = \pi r\\8 = r$
