suppose that oil spilled from a ruptured tanker spreads in a circular pattern whose radius increases as a constant 2 feet per second.

suppose that oil spilled from a ruptured tanker spreads in a circular pattern whose radius increases as a constant 2 feet per second. find a function f that models the radius of the oil spill as a function of time: r=f(t) with t greater than or equal to 0 measured in seconds. how long before the radius reaches 60 feet? how large is the radius after 1 minute? after 1 hour?
