The radius of a circle is 6 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. In this case, the radius \( r \) is 6 cm.

Substituting the value in:

\[ \text{Area} = \pi (6)^2 = \pi \times 36 \]

Using \( \pi \approx 3.14 \):

\[ \text{Area} \approx 3.14 \times 36 \approx 113.04 \]

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

\[ \text{Area} \approx 113 , \text{cm}^2 \]

So, the area of the circle is 113 cm².
