A A circular oil spill continues to increase in size.
The radius of the oil spill, in miles, is given by the
function r(t) = 0.5 + 2t, where t is the time in hours.
The area of the circular region is given by the
function A(Z) = 172, where r is the radius of the
circle at time t.
Explain how to write a composite function to find
the area of the region at time t.
