Question

fiona draws a circle with a diameter of 14 meters. what is the area of fionas circle? 7π m² 14π m² 28π m² 49π m²

Explanation:

Step1: Find the radius

The radius \( r=\frac{d}{2} \). Given \( d = 14\) meters, so \( r=\frac{14}{2}=7\) meters.

Step2: Calculate the area

The formula for the area of a circle is \( A=\pi r^{2}\). Substitute \( r = 7\) into the formula: \( A=\pi\times(7)^{2}=49\pi\) \(m^{2}\).

Answer:

\(49\pi\ m^{2}\)
