Answer 1

The volume of a sphere is 5,000 m3. What is the surface area of the sphere to the nearest square meter? (1 point)62,832 m2
1,517 m2
3,033 m2
195 m2

Answer 2

what is the formula of sphere volume? what is the formula of surface are of sphere?

Answer 3

I have no idea

Answer 4

look at cheat sheet or formula sheet

Answer 5

not to be rude but please could you allow Noemi to explain , she is good at expaining to me .

Answer 6

theres nothing to explain to be honest, you need to know formulas and then use them (of course you can come up with formula yourself but its rather hard so I don't think teachers expect that from you) but as you wish, ciao

Answer 7

Thank you

Answer 8

I am confused now, the method I used didn't give me a matching answer with you. I'll try to figure out what's wrong.

Answer 9

volume of sphere\[V=\frac{4}{3}\pi r^3\]
get radius r\[5000=\frac{4}{3}\pi r^3\]
\[\frac{3750}{\pi}=r^3\]
\[r=\sqrt[3]{\frac{3750}{\pi}}\]
area of sphere
\[A=4\pi r^2\]
insert r
\[A=4\pi \left(\sqrt[3]{\frac{3750}{\pi}}\right)^2\approx1414\]
given answers are not always correct

Answer 10

That's the procedure I used @Tomas.A
I wasn't sure if it right though.
Lexi Tomas is right(:
