Question

A rectangular sheet of paper 88 cm x 40 cm is rolled along its length and a cylinder is formed.
Find the volume of the cylinder so formed.
1320 cm. Find its diameter.
the radiof two cylinders is 2.2 :​

Answer 1

Step-by-step explanation:

Height of cylinder = Width of sheet =BC=22 cm

Circumference of top = 2πr = Length of sheet =AB=36 cm

⇒r=

2π

36

Now, volume = πr

h

=π×(

2π

36

)

×22

=

4×22

36×36×7×22

=2268cm
