Answer:
<em>A= 1256</em>
Step-by-step explanation:
<u>The formula for area of a circle is </u>![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. <em>40/2 = 20. </em>
<em>2. </em>Then, plug in the values into the area formula. <em>A= 3.14</em>![(20^{2})](https://tex.z-dn.net/?f=%2820%5E%7B2%7D%29)
3. Solve.<em> A= 1256</em>. (Remember that 20 squared is <em>20x20</em>)
