Question

score: 0/3 penalty: 0.25 off question watch video the radius of a circle is 5 in. find its area to the nearest whole number.

Explanation:

Step1: Recall 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 \(r = 5\) in. Substitute \(r = 5\) into the formula: \(A=\pi\times(5)^{2}=\pi\times25\).

Step3: Calculate the value

Using \(\pi\approx3.14\), we have \(A = 3.14\times25=78.5\).

Step4: Round to the nearest whole number

Since \(0.5\) is the mid - point for rounding, when we round \(78.5\) to the nearest whole number, we get \(79\).

Answer:

\(79\) square inches.
