Question 198115: The radius of a can soup is 2 in. and the height is 7 in.
Is there enough information in the diagram to calculate the area of the label? If so, calculate the area of the label (Use pi = 22/7) If not, explain what additional information would be necessary.
Answer by RAY100(1637)   (Show Source):
You can put this solution on YOUR website! Remember that the circumference is = 2*pi*radius
.
If we unwrapped the label,, it would be a rectangle (LA or lateral area),,,whose side is the height (7),,,and whose length is the circumference,,(2piR)
.
LA = 2 * pi * r * h = 2 * 22/7 * 2 * 7 = 88 sq in
