Question

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

Explanation:

Step1: Substitute the radius into the formula

Given \( r = 14\) in and \( A=\pi r^{2}\), substitute \(r\) into the formula: \(A = 3.14\times14^{2}\).

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

\(14^{2}=14\times14 = 196\). So the formula becomes \(A=3.14\times196\).

Step3: Multiply to find the area

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

Answer:

\(615.44\)
