square inches.

Respuesta :

Answer:

[tex]Area = 314\ in^2[/tex]

Step-by-step explanation:

Given

[tex]D = 20\ in[/tex] -- Diameter

Required

Determine the area

First, we calculate the radius (r)

[tex]r = \frac{1}{2}D[/tex]

[tex]r = \frac{1}{2}*20[/tex]

[tex]r = 10[/tex]

The area is then calculated as:

[tex]Area = \pi r^2[/tex]

[tex]Area = 3.14 *10^2[/tex]

[tex]Area = 3.14 *100[/tex]

[tex]Area = 314\ in^2[/tex]
