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:

the radius of cylinder is 7 cm

Step-by-step explanation:

given,

rectangular paper

length = 44 cm

width = 6 cm

area of rectangular paper = 264 cm²

cylinder

height = 6 cm

radius = ?

since,

the width of rectangular paper is become the height of the cylinder.

imagine the length of paper forms the base of cylinder.

so,the perimeter of base of cylinder is equal to length of rectangular paper

therefore

2 π r = 44

2*22/7 * r = 44

r =( 44 * 7 )/ (22 * 2)

r = 7 cm
