Question

how do I round 2064 to the nearest square inch?

Answer 1

2064 what? i need a unit?

Answer 2

@emily.k.evans inches

Answer 3

what was the original question?
You can't round inches to square inches. Was the 2064 calculated? If you're trying to round to the nearest whole number, it would be 2064.

Answer 4

The question doesn't really make sense.... are you leaving out part of it? Linear inches don't "round" to square inches. You compute area in square inches from linear dimensions, but we need to know what the shape and dimensions you are given, are.

Answer 5

This is the question: No entry signs are to be cut from a rectangular metal sheet. Each no entry sign must have a diameter of 40 inches. How much material is left after producing the necessary signs? (Round to the nearest square inch.) Here is the picture: https://cds.flipswitch.com/tools/asset/media/472753

Answer 6

OK, now we're getting somewhere. So you need to find:

Total area of sheet - total area of cut-out circles = material remaining

Answer 7

Area of sheet is just LxW
Area of circles is pi * r^2 (where r = 20), x6

So what did you get?

Answer 8

I got 2060 sq in, but the difference may be due to different values used for π.
You should have got a decimal, which I assume you rounded to 2064, so 2064 sq in would be your area to the nearest square inch

Answer 9

You should use pi, for pi.

Answer 10

It depends. Some courses estimate to 3.14 or 22/7.
I've even seen some use 3.

Answer 11

Okay, first I got 9,600 for the total area of sheet, then I got 7,536 for the other part, Is that correct?

Answer 12

Why are you using 3.14 for pi? If you are permitted to use a calculator, should use the pi button for pi.

Answer 13

But if you were instructed to use 3.14, then yes, that's correct.

Answer 14

In which case, there is no need to round at all, because your result works out to a whole number. But if you use pi (which in my opinion is the correct way.... I can't imagine why any instructor would tell you to use 3.14, UNLESS you are not allowed to use a calculator), then you will have to round a decimal result.

Answer 15

Yeah I did use pie and this is the equation that I use: 120(80)-6(pi(20^2) which gave me 2,064. So I just leave it like that, correct? I don't need to round it?

Answer 16

You did not get 2064, if you used pi. The pi button. you get 2064 if you use 3.14, which is only an approximation of pi.

Answer 17

https://www.wolframalpha.com/input/?i=120(80)-6(pi(20%5E2))

That give you 2060.1776, which rounds to 2060 sq in
