When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A= $\pi r^{2}$ so we plug in our known variables...

we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.

r=9

A= $\pi 9^{2}$

A= $\pi$ 81

A=254.469

Evaluate:-|137|+|13|

pychu [463]

Answer:

The answer is 150

Step-by-step explanation:

I think what you mean with the numbers between the "I's" is <em>absolute value</em>. Any number is just that number, so the <em>absolute value </em>of -6, is 6. The absolute value of 24 is 24. That means it's simply 137+13, which is <u>150</u>.

Write the expression. Then, check all that apply. twice the difference of a number and six A 2-column table with 4 rows. Column

Pie

The statements that apply to the algebraic expression are

Replace “a number” with the variable, n.
The two operations are multiplication and subtraction.
The constants are 2 and 6.
The expression is written as 2(n – 6)

<h3 /><h3>How to determine the algebraic expression?</h3>

The complete question is added as an attachment

The statement is given as:

Twice the difference of a number and six

Represent the number with n.

So, the statement becomes

Twice the difference of a n and six

Twice means 2 *

So, we have

2 * difference of a n and six

Express difference as minus i.e. -

So, we have

2 * (n - 6)

Hence, the expression is written as 2(n - 6)
