$\bf \textit{surface area of a sphere}\\\\ SA=4\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ A=14650000 \end{cases}\implies 14650000=4\pi r^2 \\\\\\ \cfrac{14650000}{4\pi }=r^2\implies \cfrac{3662500}{\pi }=r^2\implies \sqrt{\cfrac{3662500}{\pi }}=r\implies 1079.73\approx r$

HI ANYONE PLEASE HELP ME IF YOU CAN,

8090 [49]

Answer:

The fraction 7/8 is really close to 1 , so Yvonne could estimate that she needs approximately 6 yards of fabric per dress. So, to make 5 dresses, she would need approximately 30 yards.

Step-by-step explanation:

I'm not entirely sure, but 7/8 is very close to a whole, so this is what I would assume.

Are cells living? or not?<br><br> 3 times 3 minus 6 (3x3-6) = ?

Arlecino [84]

Answer:

Yes, cells are living, because they make up living things, and can do what most living things are able to, like reproduce.

(3 x 3 - 6) = ?

First, multiply 3 x 3, which = 9

(9 - 6)

Then subtract 9 by 6, giving you 3.

So, :

(3 x 3 - 6) = 3
