A rectangular sheet of paper 44cm×18cm is rolled along its length and a cylinder formed . Find Curved Surface Area of the cylinder About the author Delilah
Answer: 792 cm^2 Step-by-step explanation: Length of the rectangular sheet = Base circumference of the cylinder = 44cm Breadth of the rectangular sheet = Height of the cylinder = 18cm So, Curved Surface Area of the cylinder [tex] = 2\pi rh[/tex] [tex] = 44 \times 18 \: {cm}^{2} [/tex] [tex] = 792 \: {cm}^{2} [/tex] Hence, Curved Surface Area of the cylinder is 792 cm^2.

Step-by-step explanation: Let the height be 18cm therefore, circumference of base 44cm so, radius is 44*7/2*22 = 7 CSA of cylinder= 2πrh = 2*22/7*7*18 = 792 Reply
Answer:
792 cm^2
Step-by-step explanation:
Length of the rectangular sheet = Base circumference of the cylinder = 44cm
Breadth of the rectangular sheet = Height of the cylinder = 18cm
So, Curved Surface Area of the cylinder
[tex] = 2\pi rh[/tex]
[tex] = 44 \times 18 \: {cm}^{2} [/tex]
[tex] = 792 \: {cm}^{2} [/tex]
Hence, Curved Surface Area of the cylinder is 792 cm^2.
Step-by-step explanation:
Let the height be 18cm
therefore, circumference of base 44cm
so, radius is 44*7/2*22
= 7
CSA of cylinder= 2πrh
= 2*22/7*7*18
= 792
