question
the radius of a circle is 13 cm. find its area in terms of π.
answer attempt 1 out of 2
a = cm²

Explanation:

Step 1: 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.

Step 2: Substitute the given radius into the formula.

Given \(r = 13\) cm. Substitute \(r=13\) into \(A=\pi r^{2}\), we get \(A=\pi\times(13)^{2}\).

Step 3: Calculate the value of \(r^{2}\).

\((13)^{2}=13\times13 = 169\). So \(A = 169\pi\).

Answer:

\(169\pi\)
