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

First, we should find out what the circumference of one can is and then multiply it by two, because they ask us about two cans.

The formula for calculating the circumference is:
C = 2πr

Good news - we have r! r equals 8.3 cm.
So the circumference of one can, hence length of one piece of paper, equals 2π * 8.3 = 16.6π. Length of two pieces of paper is the result of this multiplication: 2 * 16.6π = 33.2π

(m+11n)^2=(m+11n)(m+11n)=m^2+11mn+11mn+121n^2=m^2+22mn×121n^2 for example; use foil: (a+b)(a+b)first. a^2outside. abinside. ablast. b^2
