Answer:

254.4 in²

Step-by-step explanation:

Area of a circle is given by the formula:

\pi r^{2}

Our radius is 9 so we substitute this into the equation:

π(9)² = 81π

81π = 254.4 in²

Answer:

254 cm^2.

Explain:

The area of a circle is given by pi r squared. Pi has a constant value of 3.14. And the radius of the circle is 9 cm. The area equals pi R² equals 3.14 × 9² CM squared. 3.14 × 81 = 2.54.34cm^2 equals 254cm^2.

Which of the following is an equation for a line that is NOT parallel to the other three?
galben [10]

The equation of the line that is not parallel to others is (C) 2x-3y= -1

<h3>How to determine the equation of the line is not parallel?</h3>

From the question, we have the following parameters that can be used in our computation:

A) 3x-2y=5

B) -3x+2y=9

C) 2x-3y= -1

D) -3x+2y=8

Make y the subject in equations

So, we have the following representation

A) y = 3/2x - 5/2

B) y = 3/2x + 9/2

C) y= 2/3x + 1/3

D) y = 3/2x + 4

As a general rule of linear equations

Parallel lines have equal slope

A linear equation is represented as

y = mx + c

Where

slope = m

Using the above as a guide, we have the following:

A) y = 3/2x - 5/2 ⇒ slope = 3/2

B) y = 3/2x + 9/2 ⇒ slope = 3/2

C) y= 2/3x + 1/3 ⇒ slope = 2/3

D) y = 3/2x + 4 ⇒ slope = 3/2

Hence, the line that is not parallel is (c)

Writr a real word promblem for the equation 15w equals 45
morpeh [17]
15 pounds of peanuts cost 45 dollars
how much does 1 pound of peanuts cost
ok

15 times (cost per pound)=45
represent cost per pound with 'w'
15 times w=45
15w=45
divide both sides by 15
w=45/15
w=3
cost is $3 per pound

Rewrite 1/5:1/2 as a unit rate
yulyashka [42]

Hey there! I'm happy to help!

The unit rate is how much stuff there is per 1 unit. All ratios can be rewritten as fractions, this one could be 0.2/0.5. The word per means divide, and fractions are basically dividing. So, we want the denominator to be 1.

To get 0.5 to 1, we multiply by 2. So, we will multiply the fraction by 2/2.

0.2/0.5(2/2)=0.4/1

Therefore, the unit rate is 0.4/1 or 0.4:1 or 0.4 per 1.

Have a wonderful day! :D
