2(pi r 2) + (2 pi r)* h
The formula is AL = 2*Pi*radius*height
Wrong, it's True. (Apex)
Surface area of a cylinder = (pi) x (diameter of the circular end) x (length)
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.
the circumfrance of the base x the height of the cylinder
The formula is AL = 2*Pi*radius*height
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)
I know the surface area. 2B+ lateral (Ph)
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 sphere has only a surface area and no lateral area since it has no base. The surface area is 4(pi)r2.
A cylinder with radius 5 and width 10 has a lateral area of about 314.16 units2
