Oil is leaking from an oil tanker, and an expanding circle of oil is spreading on the ocean. the radius, r, of the circle measured in inches is modeled by the function r(s)=3/s , where s is time in seconds. the area of the spill when seconds is square inches.

Area =

Explanation:

Oil is leaking from an oil tanker and an expanding circle of oil is spreading on the ocean.

The radius of circle r is modeled by the function .

We need to calculate the area of spill when s=5 in.

Formula:

where, .

Now, we put s=5 into A

we get,

the workers who do no drive has no reasonable reason to buy gasoline due to they don't have anything to use it for
