a rectangular sheet of length 44cm and breath is 11cm is folding along it's length to form a cylinder.find it's volume
Answers
Answer:
as rectangular sheet is rolled along it's length circumference of the base circle of cylinder is
2 x 22/7 x r=44
r=7
now volume of cylinder= 22/7 x r square x h
= 22/7 x 7 x 7 x 11
=2079 cm cu

Answer:
The volume is 1694 cm³
Step-by-step explanation:
Length of rectangular sheet = 44 cm
Breadth of rectangular sheet = 11 cm
When a rectangular sheet is folded along its length to form a cylinder.
Then,
Length = circumference
Breadth = height
So,
★ Circumference = 44 cm
2 π r = 44
★ Find the radius :
⇒ 2 π r = 44
⇒ 2 × 22 / 7 × r = 44
⇒ 44 / 7 × r = 44
⇒ 44 r = 44 × 7
⇒ 44 r = 308
⇒ r = 308 / 44
⇒ r = 7
Radius = 7 cm
Height = 11 cm
★ Volume of cylinder = π r² h
⇒22 / 7 × 7 × 7 × 11
⇒ 22 / 7 × 49 × 11
⇒ 22 / 7 × 539
⇒ 1694
Therfore,
The volume is 1694 cm³
