Question

a rectangular paper of length 44 cm and width 6 cm is rolled to form a cylinder of height equal to width of the paper find the radius of the cylinder so rolled​

Answer 1

Answer:

7 cm................................................

Answer 2

The radius of cylinder is 7 cm

Step-by-step explanation:

A rectangular paper of length 44 cm and width 6 cm is rolled to form a cylinder of height equal to width of the paper.

The height of cylinder is equal to width.

So, h = 6 cm

A cylinder rolled through length.

So, the circumference of circular part of cylinder is 44 cm

Let radius of cylinder be r cm

$2\pi r=44$

$r=\dfrac{44}{2\pi}$

$r=7$

Hence, the radius of cylinder is 7 cm
