It is possible for some cones A and cylinders B. But in general, the assertion is false.
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).
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
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.
First, you figure out what the area of the top of the cylinder is, which in case is pi times radius squared. Then, you multiply the answer by two. Next, you find the lateral surface area of the cylinder by multiplying the circumference times the height. Since the problem only gives us the radius of the cylinder, we use the formula, two times pi times radius times the height, in order to find the lateral surface area of the cylinder. Now the final step. Add the answer you got for the first step, plus the lateral surface area of the cylinder, and this should give you the surface area of the can of soup.
true
The lateral surface area of this cylinder is approximately 859.54cm2
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.
Wrong, it's True. (Apex)
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).
The lateral surface area is 188.5 units2
A cylinder with a height of 4cm and a width of 10cm has a lateral area of about 125.66cm2
A cylinder with radius 5 and width 10 has a lateral area of about 314.16 units2
No, it never can equal one third of the lateral surface area:If the base of the cylinder and cone has radius r, and the height of the cone and cylinder has height h, then:Lateral surface area of a cone = πr√(r2+h2)Lateral surface area of a cylinder = 2πrhThe lateral surface area of a cone equals one third the lateral surface area of a cone when:πr√(r2+h2) = 1/3 x 2πrh⇒ √(r2+h2) = 2/3h⇒ r2+h2 = 4/9h2⇒ r2 = -5/9h2But a square number can never be negative, so this is impossible.However, the volume of a cone is one third the volume of the cylinder with the same radius r and height h:Volume cone = 1/3πr2hVolume cylinder = πr2h
The lateral surface area of a cylinder with the radius of 7 feet and height of 16 feet equals 703.72 feet2
the circumfrance of the base x the height of the cylinder
The lateral surface area of a cylinder with a height of twelve inches and a radius of seven inches equals 527.79 square inches.
