For this case we have that by definition, the area of a circle is given by:


A = \pi * r ^ 2

Where:

A: It is the radius of the circle.

If they tell us that the diameter is 17 inches, then the radius is 8.5 inches. Substituting:


A = \pi * (8.5) ^ 2\\A = 226,865

If we round up, we have that the area is:

226.87 square inches

Answer:

Option C
