A circle has the diameter of 16 cms. What is it's area?
-
200.96 I think A= pie x r x r

Area of circle = pi x (r squared)
r is the radius ( diameter = 2r)
Pi (not pie) is a constant, approximately 3.1415927
Area = 3.1415927 x (8 x 8)
r is the radius ( diameter = 2r)
Pi (not pie) is a constant, approximately 3.1415927
Area = 3.1415927 x (8 x 8)
