Explain what each line of code does: a) const PI = 3.14

b) radius = float(input(“Enter radius: ”))

c) Area = PI * radius * radius

d) print(area)

i thinks its c not sure tho

these  signals travel  down a part of the neuron called the axon, which is like a wire that carries the  signal  to othernerve  cells. on average a  nerve  cell sends a  signal  at about 50 meters per second, which is over 100  miles  an hour!

a few, because i should have plenty.
