A rectangular sheet of paper of length 35 cm and breadth 28 cm is folded in two ways to form a cylinder. Find the difference in the volumes of cylinders formed.
​

At first

Way 1

Let's take height as breadth and Length as circumference

35 = 2 × 22/7 × r

35 × 7 = 2 × 22 × r

245 = 44r

245/44 = r

4.5 cm ≈ r

Now,

Volume = πr²h

Volume = 22/7 × 5.5² × 28

Volume = 22/7 × 30.25 × 28

Volume = 22 × 30.25 × 4

Volume = 2662 cm²

Way 2

Lets take Length as height and Breadth as circumference

28 = 2 × 22/7 × r

28/2 = 22/7 × r

14 = 22/7 × r

14 × 7/22 = r

4.4 = r

Now,

Volume = πr²h

Volume = 22/7 × 4.4² × 35

Volume = 22/7 × 19.36 × 35

Volume = 22 × 19.36 × 5

Volume = 2130 cm²

Now,

Difference = 2662 - 2130

Difference = 532 cm

Area of Circle = πr²

TSA of cuboid = 2(lb + bh + lh)

CSA of cuboid = 2h(l + b)

in order to appeal you must be able to show why the mark or classification you are appealing against is unfair, or does not represent your true academic ability. you believe your degree classification was not calculated correctly. a procedural problem over the way an exam or assessment was conducted or marked.
