Answer:
Explanation:
im gonna try my best to explain and get an answer since this question is vague :D
to find the area of a cylinder (the shape of the can): A=2πrh+2πr2
since theres no stated radius you have to divide the diameter by 2 to solve.
so plug it in from the equation above
the cans she is trying to make will all have an area of 207.4 (rounded to nearest tenth/not rounded is 207.35)
207 x 12 = 2,484.
so diana can make 12 cans using 2,484 in out of the sheet of metal she is using.
hope this helps in someway.
