Question

1. what is the formula for the area of a circle? what is the area of the circle shown below? hint..page 2 of the formula sheet. make sure to label. formula for area:____________________________ area: ____________________________

Explanation:

Step1: Write the formula for the area of a circle

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

Step2: Substitute the given radius into the formula

Given \( r = 7\) in. Substitute \( r = 7\) into \( A=\pi r^{2}\), we get \( A=\pi\times(7)^{2}\).

Step3: Calculate the value

\( A=\pi\times49\). Using \( \pi\approx3.14\), then \( A = 3.14\times49=153.86\) in².

Answer:

Formula for Area: \( A = \pi r^{2}\)
Area: \( 153.86\) in²
