Answer 1

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 $\frac{d}{2}$. D being diameter.

D = 57.

$\frac{57}{2}= 28.5$

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

$A = \pi *r^2$

$A = \pi *28.5^2$

$28.5^2$

$812.25$

$A=\pi *812.25$

$A=3.14 * 812.25$

$A = 2550.465$

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

$2550.5$
