The answer is B). graph B
Answer:
Step-by-step explanation:
length of an arc(s) = θ/360 x 2πr
where θ is the central angle and r is the radius
So if the total is $8.75, and 1 torch costs $7.66, and you bought 1 torch and two batteries, you would have to subtract 8.75 - 7.66 which is 1.09, and then divide that in half to get the price per battery.
Final answer = 1 Battery = $0.54
