The scatter-plot shows the cost of phone calls of different lengths. Based on the line of best fit what would be a reasonable conjecture for the length of a phone call that cost $10?

65 minutes
80 minutes
105 minutes
120 minutes

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

d is the only accurate one

step-by-step explanation:

where is the option given
