Answer:
Step-by-step explanation:
With this question you can imagine that you have a 6 cm tall cylindrical container and you take a piece of paper that is 4 cm by 6 cm and wrap it around the cylinder, then take the sheet of paper off whilst maintaining its shape - the paper will form the shape of a cylinder (without a top and bottom) but the two dimensional shape enclosed would be a circle and the area of this circle is what the question is asking.
Now given that the cylinder is 6 cm tall you can assume that the width of the sheet of paper that you would be wrapping around it would also be 6 cm tall and thus the length of that paper would be 4 cm (we are given the dimensions of the sheet as 4 cm x 6 cm) - this length is equal to the circumference of the circle that forms the base of the cylinder:
C = 2πr
4 = 2πr
r = 2/π
Now that we know the radius of the circle we can find its area:
A = πr^2
A = π*(2/π)^2
= 4/π
= 1.27 cm^2 (to two decimal places)
Basically with these questions you should always try to imagine them in a practical situation, it makes it a lot easier in the long run.
