The diameter of a circle is 24 cm. Find its area to the nearest whole number
To find the area of a circle, we use the formula:
Area = πr^2
where r is the radius of the circle. Since the diameter is twice the radius, we have:
r = 24 cm / 2 = 12 cm
Now we can plug in the radius into the formula:
Area = π(12 cm)^2
Area = π(144 cm^2)
Area ≈ 452.39 cm^2
Rounded to the nearest whole number, the area of the circle is approximately 452 cm^2.
