The radius of a circle is 8 cm. 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 \( r \) is 8 cm, we can calculate the area as follows:

\[ \text{Area} = \pi (8)^2 \] \[ \text{Area} = \pi \times 64 \] \[ \text{Area} \approx 3.14 \times 64 \approx 200.96 \text{ cm}^2 \]

Rounding this to the nearest whole number gives:

\[ \text{Area} \approx 201 \text{ cm}^2 \]

Thus, the area of the circle is approximately 201 cm².
