What is the area of a circle that its d=2

If diameter is 2, radius is 1

Area of circle = πr^2 so π x 1^2 

Answer = π

Diameter is 2 therefore radius is 1
Area = pi r^2
         =pi 1^2
         =pi
         =3.14

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

X=3 and y=4 is the answer
