A=+pi%2A+r%5E2

d= 16 m (all the way across the circle!), so r= 8 m.
+A+=+pi+%2A+8%5E2
+A+=+64%2A+pi+ square meters
Using pi+=+3.14, A = 200.96 approximately, which rounds of to nearest tenth to 201.0

Using the calculator value for pi,
A = 201.06, which also rounds off to 201.0

Final answer: 201.0
