4 . 8 =32
A cylinder is round and its circular area is dependant on one dimension only - its diameter or radius.
If the diameter is 4 inches then the area is Pi/4 x 42 = 4*Pi
If the diameter is 8 inches then the area is Pi/4 x 82 = 16*Pi
If you needed the surface area and the diameter was 4 inches and the height was 8 inches, then the surface area would be (circumference) x height = (Pi x 4) x 8 = 32*Pi square inches.
Of course Pi = 3.14159 to the nearest 5th decimal.

What is volume of water in a 4 inch cylinder 4 inches long?
If a cylinder has a diameter of 4 inches, then it has a radius of two inches, and the area of that circle is pi, 3.14, times radius squared which is 4 square inches, for a total of very close to 13 square inches; multiply that by the 4 inch length of the cylinder and you get 52 cubic inches.
What is the surface area of a cylinder that has a diameter of 8 inches and a height of 5 inches.?
The surface area of a cylinder is given by the formula 2Οr(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 2Ο(4)(4+5) = 2Ο(4)(9) = 2Ο(36) β 226.195 square inches.
How many cubic feet in 30 holes measuring 4 inches deep and 10 inches in diameter?
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
A rectangular prism has a volume of 726 a square base and a height of 6 inches a cylinder is placed inside the prism what is the greatest diameter this cylinder could have?
It works out as 11 inches because the square base of the prism has 4 sides of 11 inches.
