What is the area of a circle with a diameter of 4x - 24? Specifically what steps would you take?

Answer:

Step-by-step explanation:

The formula for the area of a circle is

A = πr².  We need the radius, r, to calculate the circle.

If the diameter of the circle is 4x - 24, then the radius is half that, or

2x - 12.

Then the area of the circle in question is  A = πr², or

A = π(2x -12)²

If desired, this could be expanded:

A = π(4)(x - 6)² = 4π(x^2 -12x + 36)

Answer:

12.56x^2+452.16

Step-by-step explanation:

A=pie r^2

(4x-24)/2= 2x-12 which is your radius

(2x-12)^2=4x^2+144

Pie=3.14ish

3.14(4x^2+144)

12.56x^2+452.16

Can you please help me with A and B
svetoff [14.1K]
I read:
Farm Maid Yogurt : 6 g of fat in 13 cups
Dairy Delight Yogurt: 5 g of fat in 11 cups.

(This is what I read, which does not represent realistic numbers, likely decimals are missing).

(a) Farm Maid Yogurt
6 g/13 cups = 10 g/x cups
Cross multiply: 6x = 130 => x=130/6=21.67 cups.

(b)
Farm maid : 6 g/13 cups, 6/13 in 13/13 cups => 0.4615 g/cup
Dairy Delight : 5 g / 11 cups, 5/11 in 11/11 cups => 0.4545 g/cup
=> Dairy Delight Yogurt has slightly less fat.

(c) 9 cups of Dairy Delight
5 g / 11 cups = x g / 9 cups
Cross multiply
11x=5*9 g => x=5*9/11 g = 4.09 g

(d) 3 cups of Dairy Delight & 5 cups of Farm Maid.
5 g/ 11 cups = x g / 3 cups 
Cross multiply
x=5*3/11 = 1.3636 g

5 cups of Farm Maid
6 g / 13 cups = y g / 5 cups
Cross multiply
y=6*5/13=2.3077 g

Total fat consumed = 1.3636+2.3077 g = 3.6713 = 3.671 g (to the nearest thousandth gram).

Your friend calculates the distance between points​ Q(1,5) and​ R(3,8), as shown below. What is his​ error?
borishaifa [10]

The distance between two points is the number of units between them.

The distance between Q and R is 3.61 units

<em>It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.</em>

<em />

The distance (d) between two points is:

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}

So, the distance QR is:

QR = \sqrt{(1 - 3)^2 + (5 - 8)^2}

QR = \sqrt{(- 2)^2 + (- 3)^2}

Evaluate exponents

QR = \sqrt{4 +9}

QR = \sqrt{13}

Take square root of 13

QR = 3.61

Hence, the distance between Q and R is 3.61 units

I am very confused plz help
prohojiy [21]

Answer:

a  26

b  8  2/3

Step-by-step explanation:

a)  4 1/3 * 6

Change the mixed number to an improper fraction

(3*4+1)/3 *6

13/3 *6

= 78/3

= 26


b)  2 3/5 * 3 1/3

Change the mixed numbers to  improper fractions

(5*2+3)/5   * (3*3+1)/3

13/5 *  10/3

130/15

Top and bottom divide by 5

26/3

Change back to a mixed number

3 goes into 26  8  times  (3*8 =24)   with 2 left over

8 2/3
