What is the sq. footage of a 20 ft. circle?
I'm guessing you mean 20 ft. circumference? With a 20' circumference, here's the math. C=20; C(r)=2*[pi]*r; 2*[pi]*r=20; r=10/[pi] A(r)=r2*[pi]; A=(10/[pi])2*[pi]; A= about 31.831 sq. ft.
What is the circumference of 20 divided by pi?
Circumference of 20 / pi = the diameter = 6.3662 (to nearest 4th decimal)
What is 2 pi over 2?
2 pi / 2 = pi.
What is the reciprocal of pi over two?
(pi/2)-1 = 2/pi
If the circumference of a circle is 20 inches what is the diameter?
20/Pi = 6.37 inches
What is a non-stationary signal?
A non-stationary signal is one whose frequency changes over time; e.g. human speech where frequencies vary over time depending on what words or syllables you are pronouncing. On the contrary, you have stationary signals where frequencies don't change over time; e.g. the signal: cos(20*pi*t)+cos(50*pi*t)+cos(200*pi*t) where all of the frequency components (20*pi, 50*pi, 200*pi) exist at all times.

How did you get 20 inches if the circumference is 62.8?
Circumference = (pi) x (diameter) Diameter = Circumference/pi 62.8/pi = 19.98986 (rounded) which is awfully close to 20.
What is 2 pi over 2?
2 pi / 2 = pi.
