The owner of an amusement park created a circular maze that has a diamater of 50 feet. If the owner doubles the radius of the maze, which statement describes what will happen to the circumherence and area of the maze?
a.the circumeference and area will double.
b.the circumference and area will quadruple.
+130516 Neither one
Call the original radius, r
Then the original area = pi* r^2 and the original circumference = 2pi* r
If he doubles the radius, the new area becomes pi *(2r)^2 = 4pi*r^2 = 4 times as much
But......the new circumference will just be 2pi * (2r) = 4pi*r = only 2 times as much
