It is: (2*pi*42)+(8*pi*6) = 203.062 square cm rounded to 3 decimal places
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Entire surface area of a cylinder = (2*pi*radius2)+(diameter*pi*height)
Entire surface area = (2pi72)+(14pi10) = 747.699 square units to 3 decimal places
The surface area of a right cylinder can be calculated by adding the areas of the two bases and the lateral surface area. The formula for the surface area of a right cylinder is 2πrh + 2πr^2, where r is the radius and h is the height. Plugging in the values 8 for the radius and 15 for the height, the surface area of the cylinder would be 720π square units.
If cylinder radius and cylinder length are known : (pi = 3.141592654 . . . ) > Surface area = ( (2 * pi * radius) * length )
A cylinder with a radius of 7in and a length of 3in has a total surface area of about 439.82 square inches.

Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
Entire surface area = (2*pi*42)+(8*pi*12) = 402.124 square units rounded to 3 decimal places
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Entire surface area: (pi*radius^2)+(pi*radius*slant length)
Entire surface area of a cylinder = (2*pi*radius2)+(diameter*pi*height)
A cylinder's length is 12 inches, and its radius is 6 inches. What is the surface area of the cylinder to the nearest tenth ?
The lateral surface area is 8796.46cm2
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.
