Answer:

804 cm^2

Explanation:

The area of a circle is given by the formula:

A = πr^2

where r is the radius of the circle. Since we are given the diameter of the circle, which is 32 cm, we can find the radius by dividing the diameter by 2:

r = d/2 = 32/2 = 16 cm

Substituting this value into the formula for the area of a circle, we get:

A = πr^2 = π(16)^2 = 256π

To find the approximate value of this expression in square centimeters, we can use the approximation π ≈ 3.14. Therefore:

A ≈ 256(3.14) ≈ 804

Rounding this value to the nearest whole number, we get:

A ≈ 804

Therefore, the area of the circle to the nearest whole number is 804 square centimeters.
