Question

the diameter of a circle is 2 feet. what is the circles area? round your answer to the nearest hundredth. square feet

Explanation:

Step1: Find the radius

The radius \(r\) of a circle is half of the diameter \(d\). Given \(d = 2\) feet, so \(r=\frac{d}{2}=\frac{2}{2}=1\) foot.

Step2: Calculate the area

The formula for the area \(A\) of a circle is \(A=\pi r^{2}\). Substitute \(r = 1\) into the formula: \(A=\pi\times(1)^{2}=\pi\approx3.14\) (using \(\pi\approx3.14159\) and rounding to the nearest hundredth).

Answer:

\(3.14\)
