The answer would be C: 11. Here’s why:

The price of each pen at Store A would be 49¢. ($2.45 divided by 5).

The price of each pen from store B for each of the answer choices is as follows:

A: About 55¢

B: 50¢

C: About 45¢

D: About 42¢

If they want to beat Store A’s deal with the least amount of pens involved, then choice C is the best option.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
