Question

find the area of this circle.
use 3.14 for π.
area of a circle
a = πr²
a = ? m²
round your answer to the nearest tenth.

Explanation:

Step1: Substitute the radius into the formula

Given \( r = 6\) m and \( \pi=3.14\), the formula for the area of a circle is \(A=\pi r^{2}\). Substitute \(r = 6\) into the formula: \(A = 3.14\times6^{2}\).

Step2: Calculate \(6^{2}\)

\(6^{2}=6\times6 = 36\). So the formula becomes \(A=3.14\times36\).

Step3: Multiply 3.14 by 36

\(3.14\times36=(3 + 0.14)\times36=3\times36+0.14\times36=108 + 5.04=113.04\).

Answer:

\(113.0\)
