Question

a metal sheet of length 2 cm and breadth 44 cm is rolled to form hallow pipe of length 2 cm. then the radius of that pipe is​

Answer 1

Step-by-step explanation:

Length of the sheet=Circumference of the base.

Length of the sheet=Circumference of the base.⇒44=2πr

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44×

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 2

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 ×

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 22

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cm

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinder

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cm

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cmCurved surface area=2πrh

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cmCurved surface area=2πrh=2×

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cmCurved surface area=2πrh=2× 7

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cmCurved surface area=2πrh=2× 722

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cmCurved surface area=2πrh=2× 722

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cmCurved surface area=2πrh=2× 722 ×7×20=880sq.cm

Length of the sheet=Circumference of the base.⇒44=2πr⇒r=44× 21 × 227 =7∴ Radius=7cmBreadth of the metal sheet=height of the cylinderh=20cmCurved surface area=2πrh=2× 722 ×7×20=880sq.cm∴ Curved surface area is 880sq.cm
