Oil from a drum leaks into water surrounding the drum, creating a circular oil slick 100 square feet in area.Find the scale factor of the size transformation of the oil slick when it is 450 square feet in area. Round to the nearest hundredth.Where is the center of the size transformation?
since area grows by the square of the scale factor, the factor is
√(450/100) = √4.5 or 3√5 / 10
