Boxes that are 16 inches tall are being stacked next to boxes that are 20 in inches tall.

a. what is the shortest height at which the two stacks will be the same? explain your reasoning.

b. how many boxes will be in each stack?

A. 80"     B. 5 boxes in the 16" box stack, 4 boxes in the 20" stack.

Step-by-step explanation:

A. Find the lowest common product that the two numbers share.

16, 32, 48, 64, 80

20, 40, 60, 80,

B. 80 is the 5th term of 16 and the 4th term of 20

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

the answer to your question is minor arc.
