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)
The length of a rectangle formed from the lateral surface of a cylinder is equal to the circumference of the cylinder's base. This circumference can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius of the cylinder. The height of the cylinder corresponds to the height of the rectangle. Thus, the rectangle's dimensions are the circumference of the base for its length and the height of the cylinder for its height.
The radius of the cylinder would be 0.64cm ! The radius is half the diameter - length has nothing to do with the question !
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 of a cylinder = (2*pi*radius2)+(diameter*pi*height)
Entire surface area: (pi*radius^2)+(pi*radius*slant length)
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.
