We have a rectangular sheet of paper, whose area is determined by using the formula, Area of sheet = Length × breadth. Suppose, we rolled the sheet either along the length or along the breadth, then it becomes the three dimensional shape of cylinder. The volume of this three dimensional shape can be determined by using the formula, Volume = πr²h, where r is the radius and h is the height of the cylinder as given in the figure. Now read the following questions and tick the correct option (a) If we cut the given sheet along the diagonal AC and the remaining sheet ABC revolved about the line BC, then the three dimension figure is formed in the shape of (i) cylinder (ii) cone (iii) sphere (iv) cuboid (b) Suppose we rolled the sheet either along the length or along the width such that the two parallel edges join and we have to determine the volume in two different ways. Is their any difference in their volumes ?(i ) Yes (ii) No (iii) can not say anything (iv) None of the above (c) Volu

Answer:
a) CONE.
b)(i ) Yes.
Step-by-step explanation:
We have a rectangular sheet of paper, whose area is determined by using the formula, Area of sheet = Length × breadth.
we rolled the sheet either along the length or along the breadth, then it becomes the three dimensional shape of cylinder.
The volume of this three dimensional shape can be determined by using the formula, Volume = πr²h.
where r is the radius and h is the height of the cylinder.
(a) If we cut the given sheet along the diagonal AC and the remaining sheet ABC revolved about the line BC, then the three dimension figure is formed in the shape of CONE.
(b) Suppose we rolled the sheet either along the length or along the width such that the two parallel edges join and we have to determine the volume in two different ways. Is their any difference in their volumes
(i ) Yes.
