Is 5 or 9 farther from 0?<br><br> 9 is farther from 9 than 5<br> 5 is farther from 0 than 9.

Answer:

My brains wires got crossed just reading this.

（；´д｀）ゞ

So give me a second while I try to wire them back.

...

Ok so,

Here's a little scale

0 1 2 3 4 5 6 7 8 9

^ ^ ^

Here is 0 Here is 5 And here is 9

So,

You say 9 is farther from 9 than 5. How if 9 is at 9? (っ °Д °;)っ

Can't help you there m an.

¯\_(ツ)_/¯

Then you say 5 is farther from 0 than 9.

Its actually closer to 0 than 9 is from 0. Like literally count backward and you can see you have to count less from 5 to 0 than you would for 9 to 0.

Im not sure dude.

Im a little confused now.

What were you even asking for in the first place?

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate at which the diameter decreases whe

mixas84 [53]

Answer:

The diameter decreases at the rate of 0.0796 cm/min when the diameter is 10 cm.

Step-by-step explanation:

A snowball is spherical, so it's area is given by the following formula:

$A = 4\pi r^{2}$

The radius is half the diameter so:

$A = 4\pi (\frac{d}{2})^{2}$

$A = 4\pi \frac{d^{2}}{4}$

$A = \pi d^{2}$

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate at which the diameter decreases when the diameter is 10 cm.

We have to find $\frac{dd}{dt}$ when $\frac{dA}{dt} = -5, d = 10$
