Question

find the area. 13 cm a = ? cm² a = πr² use π = 3.14

Explanation:

Step1: Substitute the values into the formula

$$A=\pi r^{2}$$
Given \(r = 13\) cm and \(\pi=3.14\), we substitute these into the formula: \(A = 3.14\times13^{2}\)

Step2: Calculate \(13^{2}\)

\(13^{2}=13\times13 = 169\)

Step3: Multiply the results

\(A=3.14\times169\)
\(A = 530.66\)

Answer:

530.66
