Answer:
The radius is approximately 3.18 cm
Step-by-step explanation:
Length of the rectangular sheet = Height of the cylinder = 176 cm
Width of the rectangular sheet = Circumference of the cylinder = 20 cm
Circumference = 2πr
20 = 2 × 22/7 × r
20/2 = 22/7 × r
r = 10 × 7/22
r = 35/11
r = 3.18 cm (approx.)
