Question

find the area. 10 m a =? m² a = πr² use π = 3.14

Explanation:

Step1: Substitute the radius into the formula

Given \(r = 10\) m and \(A=\pi r^{2}\), substitute \(r\) into the formula: \(A = 3.14\times(10)^{2}\)

Step2: Calculate the square of the radius

\((10)^{2}=10\times10 = 100\), so \(A=3.14\times100\)

Step3: Multiply to find the area

\(3.14\times100=314\)

Answer:

\(314\)
