Acircular oil slick is expanding at a rate of 2m^2/h. find the rate at which it's diameter is expanding when it's radius is 1.5m

Step-by-step explanation:

The circular oil slick is expanding at a rate of  

Let A be the area of the circular oil slick,

So, the changes in  A with respect to time (t),

Also, the change in diameter with respect to time(t),

For r = 1.5 m,

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.
