Answer:

111 in

Step-by-step explanation:

Let the remainder of the diameter is x.

Use the intersecting chords theorem:

6*x = (72/2)*(72/2)
6x = 1296
x = 216

The diameter:

d = 6 + x = 6 + 216 = 222 in

The radius:

r = 222/2 = 111 in

-5+d/3=5 solve the equation what does d equal

Aleks [24]

-5+d/3=5

d/3-5=5

d-3.5/3=5

d-15/3=5

d-15=15

(d-15)+15=15+15

d-15+15=30

d=30

Find the area of rectangle with sides 2 5/6 and 4 4/7

g100num [7]

<h3>Given :</h3>

Length = $\sf2\dfrac{5}{6}$ cm.
Breadth = $\sf4\dfrac{4}{7}$ cm.

The area of rectangle.

<h3>Solution :</h3>

Area of rectangle = Length × Breadth

$\sf=2\dfrac{5}{6}\times4\dfrac{4}{7}$

$\sf=\dfrac{17}{6}\times\dfrac{25}{7}$

$\sf=\dfrac{17\times25}{6\times7}$

$\sf=\dfrac{425}{42}$

<h3>Area of rectangle is 425/42 cm².</h3>

Find the value of x, o is the centroid

Ray Of Light [21]

Answer:

x = 14

Step-by-step explanation:

In the triangle O is the centroid.

Now, we know that the centroid divides the medians in the 2 : 1 ratio that means the distance from the centroid to the vertex and the distance from the centroid to the opposite side remains in 2 : 1 ratio.

So, from the given diagram we can write

$\frac{3x}{2x - 7} = \frac{2}{1}$

⇒ 3x = 4x - 14

⇒ x = 14 (Answer)
