hi i m sunny dhiman..

The lateral surface area of cylinder will become equal to the area of rectangle

now we have area of rectangle = 4224 cm^2

breadth (width) = 33cm

area of rectangle = l * b

4224 = l * 33

4224/33 = l

128 = l

Perimeter of rectangle = 2l+ 2b

=2 (128) + 2(33) =332cm

Previous answer was completely wrong.

Lateral area of cylinder is 4224 sq.cm. (not cu.cm. by the way)

Height is 32 cm so lateral width must be 4224/32 = 132 cm = diameter of cylinder.

Perimeter of sheet is the circumference of a 132 cm cylinder = 132*Pi = 414.6902 cm.

So final sheet size is 32 cm x 414.6902 cm.

Q: The lateral surface area of a hollow cylinder is 4224 cu cm and it is cut along its height and a rectangular sheet of width 32 cm is formed so find the perimeter of the rectangular sheet?

The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.

A cylinder with a height of 4cm and a width of 10cm has a lateral area of about 125.66cm2

The lateral surface area of a cylinder with the radius of 7 feet and height of 16 feet equals 703.72 feet2

To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).

It is possible for some cones A and cylinders B. But in general, the assertion is false.

true

The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.

It depends whether you want lateral or surface area. Lateral area is only the area of everything except the two bases. Surface area is the total area. Lateral area formula: pH or perimeter(of base) x height In this case, since this is a cylinder, the perimeter will be pi(diameter). Surface area: pH + 2B B= area of base So the equation would be: 10pi(9) + 2(pi x 5 squared)

Wrong, it's True. (Apex)

The lateral area of a right cylinder is curved surface that connects the two bases. The surface area is the total area of the curved surface and the bases.Lateral Area: The lateral area of a right cylinder with radius r and height h is L = 2pirh.Surface Area: The surface area of a right cylinder with lateral area L and base area B is S = L + 2B, or S = 2pirh + 2pir^2.

The lateral surface area, that is, the part curved in 3-dimensional space, is equal to the perimeter of one circular base multiplied by the height. The perimeter of a circle with radius 10 is 20(pi); therefore, the lateral area is 20(pi)16 = 6.0 X 102 to the justified number of significant digits.

A cylinder with a height of 4cm and a width of 10cm has a lateral area of about 125.66cm2

The lateral surface area is 188.5 units2

A cylinder with radius 5 and width 10 has a lateral area of about 314.16 units2

the circumfrance of the base x the height of the cylinder
