Question

a rectangular sheet of paper 44 cm into 20 cm is rolled along its length of form a cylinder find the total surface area of cylinder has generated

Answer 1

Answer:

Step-by-step explanation:

ength of the rectangular sheet l=44cm

breadth of the rectangular sheet b =20cm

then, the radius r of the cylinder=circumference of the base of cylinder =2pir

44=2x22/7r

44x7/44

r=7

height h of the cylinder =20cm

TSA= 2*pi*r(r+h)

2*22/7*7(7+20)

44*27= 1188 cm^2
