Question

A rectangular sheet of paper having length 88 cm and breadth 36 cm is rolled along its length and a cylinder is formed. Find the radius and height of cylinder.​

Answer 1

Answer:

Radius of the cylinder r = 14 cm

Height of the cylinder h = 36 cm

Step-by-step explanation:

Given data

A rectangle sheet of paper having length 88 cm, breadth 36 cm

is rolled along its length

Here we need to find radius and height of the cylinder

⇒ From given data the rectangle sheet is rolled along its length then the length of the sheet will become as perimeter of circular base of the cylinder

       ⇒ 2$\pi r$ = 88   [ 2$\pi r$ formula for perimeter of the circle ]

       ⇒ 2$\frac{22}{7}$r = 88

       ⇒  44/7 r =88

       ⇒ r = $\frac{88}{44}$ × 7 = 2(7) =14 cm

⇒ Radius of the cylinder = 14 cm

⇒ and the breadth of the rectangle sheet will become height of the cylinder  

⇒ height of the cylinder h = 36 cm
