Whiskeytown Lake in Whiskeytown National Recreation Area in California has a 36 mile shoreline and a surface area
of 3,200 acres.
If the lake were circular, what would be the area if it had a circumference of 36 miles?
(Give your answer in acres).
Solution to the Problem:
The answer is 66,004 acres.
C = pi * d
36 miles = pi * d
18 / pi = r
So, r = 5.7296 miles = 30,252 feet
A = 2,875,166,387 square feet
Since there are 43,560 square feet in an acre,
A = 66,004 acres.
