Circumference, C = 2 $\pi$ r. Find the radius using this formula then use it to find the area with A = $\pi$ $r^{2}$ .

OR use the formula A = $\frac{C ^{2} }{4\pi }$

Hope it helps. mark as brainliest if it does...

ziro4ka [17]

Answer:

$58x-54=468$

Step-by-step explanation:

Number of repeat customers = 40

Amount charged from each of the repeat customers = $ x

So,

amount charged from 40 customers = $ 40 x

Number of new customers = 18

As Michel charged each of the new subscribers $3 less than the amount charged from each of the repeat customers,

amount charged from each of the new customers = $ (x - 3)

So,

amount charged from 18 new customers = $ 18(x - 3)

Total amount charged from repeat and new customers = $\$[(40x)+18(x-3)]=\$40x+18x-54=\$58x-54$

As Michel collected $468 for delivering newspapers,

$58x-54=468$

A list of positive and negative numbers are in A2 through A400, and the square root of the absolute value is needed for each cel

xeze [42]

Answer:

d. =SQRT(ABS(A2))

Step-by-step explanation:

A spreadsheet will not tell you the square root (or half power) of a negative number. It only performs math using real numbers.

<h3>Considerations</h3>

Trying to take a square root of a negative number will result in a #NUM! error being shown in the result cell. Assuming you want the root of the magnitude of the numbers in column A, the value you want the root of is ABS(A2).

Using a dollar sign on a cell reference renders that portion of the cell reference fixed when the formula is copied. Referencing cell A$2 will mean you will get 399 copies of the square root of the contents of cell A2 in cells B2 through B400.

<h3>Formula</h3>

The formula that will give you the square root of the magnitude of the adjacent cell in column A will be

=SQRT(ABS(A2)) . . . . . . . . . formula for cell B2, copied to cells below
