suppose you copy the circle using a size factor of 150%.what will bet he radius,diameter,circumference,and the area of the image?
radius will be 1.5 times as big
diameter will be 1.5 times as big
but the formula for area will be pi times the radius squared. So calculate that with your circle size and then with the image size.
