Find the area of a circle with a diameter of 16.

Either enter an exact answer in terms of soruse 3.14 for

and enter your answer as a decimal

I was kind of confused, but if you just want to know the area of a circle with a diameter it's 201.06. (Also don't know how much to round by!)

Step-by-step explanation:

Using these two formulas:

A=πr^2

d=2r

(D is Diameter in this case)

(R is Radius which is 1/4)

--

A=1 / 4πd^2 = 1 / 4 * π*16^2 ≈ 201.06193

After rounding, 201.06.
