Question

find the area of a circle with radius 9 m. use the value 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the formula for the area of a circle

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

Step2: Substitute the given values into the formula

We are given that \( r = 9\space m \) and \( \pi=3.14 \). Substituting these values into the formula, we get \( A = 3.14\times(9)^{2} \).

Step3: Calculate \( 9^{2} \)

First, calculate \( 9^{2}=9\times9 = 81 \).

Step4: Multiply to find the area

Now, multiply \( 3.14 \) by \( 81 \): \( 3.14\times81=254.34 \).

Answer:

\( 254.34 \) square meters
