Question

a rectangular sheet of paper 44cm×10 cm is rolled along its length to form a cylinder find the volume of cylinder and its surface area​

Answer 1

Answer:

thanks for asking such questions

area is 440cm²

volume is 1540cm³

Step-by-step explanation:

area =lxb

area =44x10=440 cm²

now find r

total  surface area of the cylinder=2πrh

440 = 2x 22/7xrx10

2x 22/7xrx10=440

r=440x7/22x10x2

r=440x7/440

r=7cm

now find the volume

volume =2πr²h

volume=2x22/7x7x7x10

volume=22x7x10

volume=1540cm³
