he radius of a circular oil slick expands at a rate of 8 m/min. (a) How fast is the area of the oil slick increasing when the ra
dius is 26 m?
1 answer:
If it's expanding 8m per minute, then you have to multiply 8 by 26.
1 minute = 8 m
2 minutes = 16 m
5 minutes = 40 m
10 minutes = 80 m
26 minutes = 208
8 * 26 = 208
So when it reaches 26 m in length, it'll be expanding 208m per minute.
