The radius of a circle is 10 m. Find its area to the nearest whole number.

1 answer

To find the area of a circle, you can use the formula:

\[ \text{Area} = \pi r^2 \]

where \( r \) is the radius of the circle. Given that the radius \( r = 10 \) m, we can substitute this value into the formula:

\[ \text{Area} = \pi (10)^2 = \pi \times 100 \]

Calculating this gives:

\[ \text{Area} \approx 3.14159 \times 100 \approx 314.159 \]

Rounding this to the nearest whole number, the area of the circle is approximately:

\[ \text{Area} \approx 314 \text{ m}^2 \]

Thus, the area of the circle is 314 m².
