In 2010, an oil explosion spilled millions of gallons of oil in an area. The oil slick took the shape of a circle. Suppose that the area A (in square miles) of the circle contaminated with oil can be determined using the function A(t) = 0.26m² where t represents the number of days since the rig exploded. (a) Identify the dependent and independent variables. (b) Evaluate A(22) and explain what A(22) means.
