In May, the groundskeeper at Spring Lake Golf Club built a circular green with an area of 70π square feet. In August, the groundskeeper doubled the distance from the center of the green to the edge of the green. What is the total area of the renovated green?
Options:
A) 1000π	B) 400π	C) 280π	D) 200π	E) 20π
Area = πR^2, so doubling the radius results in an area that is 4 times the original area.   4(70π) = 280π   The answer is 280π.
