    The area of the circle is A. 176 square centimeters.

    Step-by-step explanation:

    Step 1:

    The area of any given circle is π times the square of the radius.

    The radius of this circle is equal to 15 centimeters, so the radius is \frac{15}{2} = 7.5 centimeters.

    The area of the circle = \pi r^{2}.

    Step 2:

    By taking π = 3.1415, we get

    The area of the given circle = 3.1415 (7.5^{2} ) = 3.1415(56.25) = 176.7093.

    The area of the circle with a radius of 7.5 cm is 176.7093 square cm. Rounding this off, we get the area as 177 square cm. The closest option to the area is option A.
