Answer 2

Answer and Step-by-step explanation:

We are told that the circumference is 20, and we are asked to find the area.

The equation for circumference is:

C = 2
`\pi`r

We can plug in 20 and solve for r.

20 = 2
`\pi`r

Divide by 2 on both sides.

10 =
`\pi`r

Now divide by
`\pi` on both sides.

`(10)/(\pi )` = r

Now, we can plug this into the area equation:

A =
`\pi`
`r^(2)`

A =
`\pi`
`((10)/(\pi ) )^(2)`

A =
`\pi`
`(100)/(\pi ^(2) )`

A =
`(100\pi )/(\pi ^(2) )`

A =
`(100)/(\pi )`

Now, we put this into the calculator to solve.

We get:

31.830988618379067153776752674503

We are then told to round to the nearest whole number.

8 is greater than 5, so we round up.

32 is the answer (The Last Answer choice)
