Diameter is 8, hence radius is 4
the base of a cylinder is also a circle. so we take the formula for area of a circle which isπr2
3.14 x (4)2= 3.14x 16= 50.24
The curved surface area of this cylinder is 251.33 units2
The curved surface area is 301.6 units2
40pi or about 125.6
The diameter cannot be "8 in and 5 in".
The surface area of a cylinder that has a height of 7 centimeters and a diameter of 8 centimeters is 276.46cm2
A cylinder with a height of 10 inches and a diameter of 8 inches has a surface area of 351.86 square inches.
The surface area is 408.41 units2
Entire suface area = (2*pi*42)+(8*pi*40) = 1105.841 sq ins rounded to 3dp
9
The curved surface area is 502.65m2
It is 226.08 cubic units.
