The diameter of a circle is 24 cm. Find its area to the nearest whole number.

Answer 1

To find the area of a circle, we use the formula:

Area = πr^2

Given that the diameter of the circle is 24 cm, we can find the radius by dividing the diameter by 2:

Radius = 24 cm / 2 = 12 cm

Now we can substitute the radius into the formula to find the area:

Area = π(12 cm)^2
Area = π(144 cm^2)
Area ≈ 3.14 x 144 cm^2
Area ≈ 452.16 cm^2

Therefore, the area of the circle is approximately 452 cm^2.
