the diameter of a sphere is 20.3m .

<u>Step-by-step explanation:</u>

Here we have , a sphere with a volume of 4397 m^3 . We need to find the diameter of sphere . Let's find out:

We know that ,  Volume of sphere is given by formula as :

⇒ Volume =\frac{4}{3}\pi r^3   .......(1)

According to question we have following parameters as :

Volume = 4397m^3\\Radius = \frac{Diameter}{2}

Putting these values in we get:

⇒  Volume =\frac{4}{3}\pi r^3

⇒  4397 =\frac{4}{3}\pi (\frac{D}{2}) ^3

⇒  4397 =\frac{4}{3}\pi (\frac{D^3}{8})

⇒  4397 =\pi (\frac{D^3}{6})

⇒  D^3 =6 (\frac{4397}{\pi})

⇒  D^3 =6 (\frac{4397}{3.14})

⇒  D^3 =8402

⇒  D =\sqrt[3]{ 8402}

⇒  D =20.3m

Therefore , the diameter of a sphere is 20.3m .

The diameter of a sphere is 20.32 m

<u>Explanation:</u>

Given:

Volume of the sphere, V = 4397m³

Diameter, D = ?

We know,

Volume of the sphere = \frac{4}{3} \pi r^3

Where,

r = radius of the sphere

On substituting the value in the formula we get:

4397 = \frac{4}{3} \pi (r)^3\\\\r^3 = \frac{4397 X 3}{4\pi } \\\\r^3 = 1049.7 m^3\\\\r = 10.16m

Diameter = 2 X radius

D = 2 X 10.16 m

D = 20.32 m

Therefore, the diameter of a sphere is 20.32 m

M is the midpoint of YZ. If YM = x + 3, and YZ = 3x -1, find MZ
Elenna [48]
2(x+3)= 3x-1
2x+6=3x-1
X=7
Therefore
YM = 7+3= 10
And by definition of midpoint YM=MZ so MZ=10

Answer:

I think it might be C but I'm not 100% sure!

Step-by-step explanation:

You have to find a line of best fit (a line through the dots) but it's kind of tricky to do that so I think it's probably C but it could also be A. Just use your best judgement on this one!
