The diameter cannot be "8 in and 5 in".

40pi or about 125.6
A cylinder 10 feet high and 5 feet in radius has a surface area of 471.24ft2
Of course the diameter of a cylinder with a diameter of 8 cm is 8 cm, but I suspect you were asking about volume or surface area.First, the measurements should be converted to the same units. Since there are 2.54 centimeters per inch, the cylinder has a diameter of 8 cm and a height of 12.7 centimeters.The volume of a cylinder is pi * (1/2 d)^2 * h, so the volume of cylinder with diameter 8 cm and height 5 inches is pi * 16 * 12.7 = 997.46 cubic centimeters.The surface area of a cylinder is (2*pi*r*h) + (2*pi*r^2) = (in our case) 556.06 square centimeters.
Total surface area of the cylinder: (2*pi*5^2) + (10*pi*9) = 140*pi square units
The cylinder's total surface area is about 227.77 units2
The curved surface area is 125.66 square inches.
207.2
Total surface area is 226 square inches and the curved surface area is 126 square inches.
The surface area of a cylinder is given by the formula 2πr(r+h), where r is the radius and h is the height. In this case, the radius is half the diameter, so it is 4 inches. Thus, the surface area of this cylinder is 2π(4)(4+5) = 2π(4)(9) = 2π(36) ≈ 226.195 square inches.
40pi or about 125.6
Surface area excluding the bases: 20*pi*5 = 100*pi square inches
Total surface area: (2*pi*9)+(pi*6*5) = 48*pi square inches
The surface area of a cylinder with the radius 16 and a height of 5 is 2,111.15 units2
The surface area is 314.16 inches2
A cylinder whose radius is 5 and height is 7 has a surface area of 377 units2
The surface area is 88 units2
