Question

find the area. 8 in a = ? in² a = πr² use π = 3.14

Explanation:

Step1: Substitute the radius into the formula

$$A = \pi r^{2}$$
Given \(r = 8\) and \(\pi=3.14\), so \(A = 3.14\times8^{2}\).

Step2: Calculate \(8^{2}\)

\(8^{2}=8\times8 = 64\). Then \(A = 3.14\times64\).

Step3: Multiply 3.14 and 64

\(3.14\times64=(3 + 0.14)\times64=3\times64+0.14\times64=192 + 8.96=200.96\).

Answer:

200.96
