Question

What is the area of a circle with a radius of 12 feet? Estimate the
area to the hundredths place using 3.14 for π. (1 point)
113.04 square feet
75.4 square feet
452.2 square feet
452.16 square feet

Answer 1

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

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

Where \( \pi \) is approximately 3.14 and \( r \) is the radius of the circle.

Given that the radius \( r \) is 12 feet, we can calculate the area as follows:

\[
\text{Area} = 3.14 \times (12^2)
\]

Calculating \( 12^2 \):

\[
12^2 = 144
\]

Now plug that back into the formula:

\[
\text{Area} = 3.14 \times 144
\]

Calculating the multiplication:

\[
\text{Area} = 452.16 \text{ square feet}
\]

So the area of the circle with a radius of 12 feet is **452.16 square feet**.
