Question

which equation can be used to find the radius of a circle with an area of 113.04 square inches? use 3.14 for π. 113.04 = (3.14)² r = 113.04 × 3.14 113.04 = 3.14r²

Explanation:

Step1: Recall the area formula of a circle

The formula for the area \( A \) of a circle is \( A=\pi r^{2} \), where \( A \) is the area, \( \pi \) is the mathematical constant (here \( \pi = 3.14 \)) and \( r \) is the radius of the circle.

Step2: Substitute the given values

We know that the area \( A = 113.04 \) square inches and \( \pi=3.14 \). Substituting these values into the formula \( A = \pi r^{2} \), we get \( 113.04=3.14r^{2} \).

Answer:

\( 113.04 = 3.14r^{2} \)
