# Daily Challenge #66

Today’s daily challenge will be again a bit easy. And again it will be maths.

So, this is explained very fast: You will have to make a procedure that, when the radius of a sphere is given, it should return the volume and the surface as a list.

Examples:

• 4.188,79… (volume)
• 1256,6… (surface)

Your program should return rounded list items (not like me ).

As always, stay safe and haaaaappy koding!

And also sorry if someone suddenly woke up in his dreams bc my topic was notified to him. #EU!

My Solution

I don’t know how you found the surface 314,2 for radius 10. I think you forgot to multiply with 4.

This is too easy, and while creating daily challenge select the tag to dailly challenge

And my solution is same as George but I just use `round` block instead of `format as decimal`

And to reduce block we can use relation of surface to volume ratio = 3/r

Yes I could reduce also the blocks by a lot but i wanted to show the formulas clear.

Yes, that’s right.

I know, but watch this one:

Yeah this was alo pretty easy, wasn’t it? I am sorry, but too hard challenges are not good, too.

It was selected. Every DC is selected as #discuss and #daily-challenge. I don’t know what you mean.

It was. But, let’s don’t hijack this topic, It’s ther now, so why do we care?

Let’s live today with looking to our future, but not to our silly mistakes we did in the past.

Why rounded? For this kind of information i prefer to have also the decimal part.

2 Likes

or if we simply say the concept of significant figures?

You can round it on several digits after the comma, but who likes to see a unreounded, long number, that makes no sense.

That’s why why i format it with 2 decimal only
