What is the circumference of the circle if r = 3.5 feet? Use 22 7 for π.45 pts

Natasha_Volkova [10]

We know, Circumference of a Circle = 2πr
C = 2 * 22/7 * 3.5
C = 2 * 22/2
C = 2 * 11
C= 22

In short, Your Answer would be 22 Feet

Hope this helps!

How do i solve this

The ratio is 2:3 for the side lengths of the triangles.

so 6:9 is one side and 5:x would be the other side

2/3 of five is 3.33 and multiplying that by 2 gives you 6.67

Instructions: Find the missing length indicated.

nata0808 [166]

Answer:

x = 12

Step-by-step explanation:

By applying geometric root theorem in the given triangle,

$\frac{BD}{DC}= \frac{AD}{BD}$

$BD^2=AD\times DC$

$x^{2} =16\times 9$

$x=\sqrt{144}$

$x=12$

Therefore, x = 12 will be the answer.

Multiply this expression and check:(4y^3+4y^2+8)(6y-4)

emmasim [6.3K]

(4y³ + 4y²+8)(6y - 4)

Simplify.

24y⁴ - 16y³ + 24y³ - 16y² + 48y - 32

Add like terms.

24y⁴ + (-16y³ + 24y³) -16y² + 48 - 32

Simplify.

24y⁴ + 8y³ - 16y³ + 16

Points A, B and C make the triangle triangle ABC and are at the coordinates A(- 4, 3) , B(- 48, 17) and C(22, - 53) . Point D is

The equation of the median in standard form is; 9y - 38x = 179.

<h3>What is the equation of the media in standard form?</h3>

It follows from the task content that the point D is the midpoint of segment BC; Hence, the coordinates of point D given the coordinates of B and C above are given as; D(-13, -35).

The equation of the median which is the line joining points A and D is therefore determined as follows;

Slope = (-35-3)/(-13-(-4)) = 38/9

38/9 = (y-3)/(x+4)

9y -27 = 38x + 152

9y - 38x = 179.
