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)

452.16 square feet
113.04 square feet
452.2 square feet
75.4 square feet

Explanation:

Step1: Recall the formula for the area of a circle

The formula for the area \( A \) of a circle is \( A = \pi r^2 \), where \( r \) is the radius of the circle.

Step2: Substitute the given values into the formula

We are given that the radius \( r = 12 \) feet and \( \pi = 3.14 \). Substituting these values into the formula, we get \( A = 3.14\times(12)^2 \).

Step3: Calculate \( 12^2 \)

First, calculate \( 12^2 = 144 \).

Step4: Multiply by \( 3.14 \)

Now, multiply \( 3.14 \) by \( 144 \): \( 3.14\times144 = 452.16 \).

Answer:

A. 452.16 square feet
