Question

a rectangular piece of paper of dimensions 88 cm by 5 cm is rolled along the length to form a cylinder find the volume of the cylinder formed

Answer 1

Answer is in picture.

Answer 2

Answer:

Length of rectangle = Circumference

Circumference = 88 cm

Height = Breadth

Height = 5 cm

$c = 2\pi \: r$

88 = 2×22/7×r

( Transpose 2×22/7 to LHS )

88 × 7/2×22 = r

14 cm = r

$volume = \pi \: r {}^{2} h$

Volume = 22/7 × 14^2×5

= 22/7×14×14×5

= 22 × 2 × 14 × 5

= 3080 cm^3

Therefore volume = 3080 cm^3
