Question

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

Explanation:

Step1: Find the radius

The diameter is \(8m\), so the radius \(r=\frac{8}{2}=4m\)

Step2: Calculate the area

Using the formula \(A = \pi r^{2}\), substitute \(r = 4\) and \(\pi=3.14\)
\(A=3.14\times4^{2}=3.14\times16 = 50.24\)

Answer:

\(50.24\)
