Wrong, it's True. (Apex)
Two hemispherical ends = 4*pi*radius2 Lateral surface area of the cylinder = 2*pi*r*lenght of cylinder Work both out separately and the sum of them will give you the total surface area in square units.
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
2(pi r 2) + (2 pi r)* h
The formula for the area of a rod, which is a cylinder, is given by A = 2πrh + 2πr^2, where A is the total surface area, r is the radius of the rod, and h is the length of the rod. The first term 2πrh represents the lateral surface area of the cylinder, which is the curved surface area, and the second term 2πr^2 represents the area of the two circular bases of the cylinder. By summing these two terms, we obtain the total surface area of the rod.
The lateral surface area of this cylinder is approximately 859.54cm2
true
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
The lateral surface area of a cylinder with the radius of 7 feet and height of 16 feet equals 703.72 feet2
It is possible for some cones A and cylinders B. But in general, the assertion is false.
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.
