Question

find the area.
10 m
a = ? m²
a = πr²

Explanation:

Step1: Substitute the radius into the formula

The formula for the area of a circle is \(A = \pi r^{2}\), and the radius \(r = 10\) m. So, \(A=\pi\times(10)^{2}\).

Step2: Calculate the value

\((10)^{2}=100\), and taking \(\pi = 3.14\), then \(A = 3.14\times100\).

Answer:

\(314\)
