Question

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

Explanation:

Step1: Substitute the radius into the formula

$$A = \pi r^{2}$$
Given \(r = 14\) in and \(\pi=3.14\), we have \(A = 3.14\times14^{2}\).

Step2: Calculate \(14^{2}\)

\(14^{2}=14\times14 = 196\).

Step3: Multiply by \(\pi\)

\(A=3.14\times196\).
\(3.14\times196=(3 + 0.14)\times196=3\times196+0.14\times196=588+27.44 = 615.44\).

Answer:

615.44
