Question

a seafood company produces cans of tuna. each can gets wrapped with a paper label. if every can has a radius of 8.3 centimeters, what is the approximate length of the paper required to cover two cans?

Answer 1

The circumference c of a circle with radius r is:

`c=2\pi r`
The total length of paper required to cover two cans is given by:

`2*\pi*8.3*2=104.3\ cm`

Answer 2

The answer is 104.3 cm.

Explanation:

In order to determine the answer, we have to know about the form of the can. In general, The can form is a cylinder, so we have to calculate the length of the contour.

The base of the can is a circle, so the contour is the perimeter of the circle.

The perimeter is:

`P=2\pi R`

R: radius of the circle

Then, we know that the radius is 8.3 cm and also we have to cover two cans:

L=length of the two covers

`L=2P=2*(2\pi R)=4\pi *8.3=104.3`

Finally, the answer is 104.3 cm.
