What is the volume of a hemisphere with a radius of 1.6 and height of 6.2?

1 answer:

6 0

You can find the area of a hemisphere by using the following equation

V = (2/3) (pi)*r^3

so V = (2/3) (pi)*1.6^3

Which comes out as 8.5786423394 or 8.6

What is x for the the problem y=6x + 8

Misha Larkins [42]

If Y is 8, we solve by subtracting 8 on both sides,

0 = 6x

Divide by 6,

0 = x

x is equal to 0

Step-by-step explanation:

180 -angled triangle,

180-56 = 124

124/2 = 62 (each corner of the right triangle)

then find the corner below

the rectangle has right angles on the right side

x = 90-62

= 28

Solve xy − 2 = k for x.

MA_775_DIABLO [31]

Isolate x
So xy - 2 = k
Then
xy = k + 2

x = (k+2)/y

How would you write a decimal that is less than five Ten thousandths

asambeis [7]

Five ten-thousandths looks like this: 0.0005

All of these are less:

0.0004
0.0003
0.0002
0.0001
0.00001
0.000001
.
.
etc.

Please help and thank you!

The conversion is

$x = r \cos \theta$

$y = r \sin \theta$

$\dfrac y x = \tan \theta$

We're given the fairly unusual

$\theta = -\frac 5 2$

It's fairly unusual because usually an angle is given in degrees or radians, and typically the radians are a fraction times pi. We'll assume radians.

$\dfrac y x = \tan \theta = \tan(-5/2) \approx 0.747$

Ah, there's our .75. The approximate answer is

$y = 0.75 x$

Third choice.

The exact answer is

$y = x \tan( -\frac 5 2)$

also a line through the origin.
