Well I would say A because it went from 8 to 38 which is plus ten.
Answer: a) about 450
Step-by-step explanation:
50 multiplied by 9 is 450 and its asking for an approximate so it would be anything near 450
Find surface area
SA=2pir^2+2hpir
h=42
r=1.5
SA=2pi1.5^2+2(42)pi1.5
SA=4.5pi+126pi
SA=130.5pi square inches
area/areacoverdperspray≤numberofsprays
130.5pi/150
2.73
so buy 3 cans because you can't get 0.73 cans
A
It’s probably-67 on the top of my head
