The radius of a circle is 9 m. Find its area to the nearest whole number.
The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
Given that the radius of the circle is 9 m, we can substitute this value into the formula:
A = π(9)^2
A = π(81)
A = 81π
Approximating π to 3.14, we get:
A = 81 * 3.14
A ≈ 254.34
Therefore, the area of the circle to the nearest whole number is 254 square meters.
