The diameter of a circle is 22 m. Find its area to the nearest whole number.

2 answers

The radius of the circle is half of the diameter, which is 22 m / 2 = 11 m.

The area of a circle is given by the formula: A = πr^2

Plugging in the values:
A = π(11)^2
A = π(121)
A ≈ 121π

Using the approximation for π as 3.14:
A ≈ 121 * 3.14
A ≈ 380.94

Therefore, the area of the circle is approximately 381 square meters when rounded to the nearest whole number.
