A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the lateral area of cylinder?

Lateral Area= (2pi)x(radius)x(height) Try imagining that you take the lateral area and unfold it from the cylinder. If you imagine it correctly you get a rectangle. The height of the cylinder is the height of the rectangle. Then the circumference is the length. SO you multiply the circumference of the base times the height.


What is a lateral square foot?

The lateral area is the surface area of a 3D figure, excluding the area of any bases. For the lateral area of a cylinder, you would take the circumference of the base multiplied by the height of the cylinder to get the lateral area of the surface. It's basically splitting a can down one side, cutting the ends off completely, rolling it out flat, and figuring out the area of the resulting rectangle.

What is the lateral surface area of a cylinder with a height of 4cm and a width of 10cm?

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 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?

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.

What is the formula to find the lateral surface area of a cylinder?

The lateral surface area of a cylinder is the area of a rectangle. In other words: when a cylinder is unravelled, you are left with a simple rectangle with width and length. Depending on what kind of cylinder you happen to have, the circumference of the cylinder could be the width or the length. Where you have a short cylinder with a wide mouth, the circumference would become the length and the h would become the w. So, think of a cylinder as a rectangle. Take a piece of paper (rectangular) and bring the ends together. What do you have?: a cylinder. Now - for the formula: Diameter= D, Circumference= C, pi= 3.14 These are the parameters of a circle. Now, in mathematics, the radius of the circle and 2 *Pi is used in order to find the circumference of the circle. So, (D * pi)= 2Pi *r = C Therefore, the circumference or perimeter equals the width and the height or h = length of a rectangle. Now, then: The Formula for the Lateral surface of a cylinder Is: (2*Pi*r)*h= A Remember that the radius is half the Diameter of a circle and must be multiplied by two in order to convert back to D or Diameter. Please, note that ( 2*pi )= 360 degrees, and that it (2*Pi) also represents one whole revolution around the perimeter of a circle. To simplify: Diameter X (3.14) X height = Lateral Area of a cylinder. I hope this is of some help!
