Answer 2

Answer:

The radius of the cylinder is 7 cm

Step-by-step explanation:

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

height of the cylinder= width of the paper = 6 cm

length of a rectangular paper becomes the circumference of the cylinder

so, circumference of the circle= 44 cm

let the radius be r cm

circumference of a circle = 2\pi r2πr

44= 2\pi r2πr

r= \frac{44}{2\pi }

2π

44r= 7 cm

hence, The radius of the cylinder is 7 cm
