The radius of a circle is 12 meters. What is the area of the circle?

Use 3.14 for π. Round to the nearest hundredth.

1 answer

The area \( A \) of a circle can be calculated using the formula:

\[ A = \pi r^2 \]

where \( r \) is the radius of the circle.

Given that the radius \( r \) is 12 meters and using \( \pi \approx 3.14 \), we can substitute these values into the formula:

\[ A = 3.14 \times (12)^2 \]

First, calculate \( (12)^2 \):

\[ (12)^2 = 144 \]

Now substitute this back into the area formula:

\[ A = 3.14 \times 144 \]

Now, perform the multiplication:

\[ A = 452.16 \]

Therefore, the area of the circle, rounded to the nearest hundredth, is:

\[ \boxed{452.16} \text{ square meters} \]
