Answer:

$Area = 314\ in^2$

Step-by-step explanation:

Given

$D = 20\ in$ — Diameter

Required

Determine the area

First, we calculate the radius (r)

$r = \frac{1}{2}D$

$r = \frac{1}{2}*20$

$r = 10$

The area is then calculated as:

$Area = \pi r^2$

$Area = 3.14 *10^2$

$Area = 3.14 *100$

$Area = 314\ in^2$
