Answer:
The radius is 7 cm
Step-by-step explanation:
The paper has width 6cm which is equal to the height of the cylinder formed. The length of the paper must be rolled to get such a cylinder.
Let l be the length of the paper
l = 44cm = circumference of the circle
circumference of the circle = 2πr
44 = 2πr
44 = 2 x 22/7 x r
44 x 7/ 2 x 22 = r
r = 7cm
