Answer:

2550.5

Step-by-step explanation:

We have a circle and are asked to find the area.

We know the diameter already, but the formula to find area requires a raidus, which is unknown to us yet.

To find radius, all you need to do is follow [tex]\frac{d}{2}[/tex]. D being diameter.

D = 57.

[tex]\frac{57}{2}= 28.5[/tex]

The radius is 28.5, now do the formula of area.

[tex]A = \pi *r^2[/tex]

[tex]A = \pi *28.5^2[/tex]

[tex]28.5^2[/tex]

[tex]812.25[/tex]

[tex]A=\pi *812.25[/tex]

[tex]A=3.14 * 812.25[/tex]

[tex]A = 2550.465[/tex]

Now we need to round to the nearest tenths, since 6 is the knowledge that we round up, round up.

[tex]2550.5[/tex]
