The diameter of a circle is 33 cm. Find its area to the nearest whole number.
To find the area of a circle, we use the formula:
Area = π * r^2
Given that the diameter of the circle is 33 cm, we can find the radius by dividing the diameter by 2:
Radius = Diameter / 2 = 33 cm / 2 = 16.5 cm
Now, we can substitute the value of the radius into the area formula:
Area = π * (16.5 cm)^2
Using 3.14 as an approximation for π, we can calculate the area:
Area ≈ 3.14 * (16.5 cm)^2
Area ≈ 3.14 * 272.25 cm^2
Area ≈ 855.78 cm^2
Rounding to the nearest whole number, the area of the circle is approximately 856 square centimeters.
