A formula for the volume is (area of base)(height)/3. The base is a circle, with area equal to pi X radius squared. It was not specified whether the given "3 Cm" for the base was radius or diameter. After clarifying that, you should be able to complete the answer for yourself.
Total surface area = (2*pi*62)+(12*pi*15) = 791.681 square cm to 3 d.p.
Cylinder volume = height 10 cm > radius 7 cm > base area of the cylinder = 153.9380400 cm2 Volume = base area x height = 1539.380400 cm 2
A mug in the shape of a cylinder has base with a radius of 4 cm How many milliliters of liquid does it hold if filled to height of 9 cm? Volume of a cylinder = area of base * height Base is a circle Area of a circle = π * radius squared The radius = 4 cm Area = 3.14 * r * r = ____ square cm Area = 3.14 * ___ * ___ = ____ square cm Volume of a cylinder = area of base * height You know area of the base and the height = 9 cm. Volume of a cylinder = ______ * _____ = _____ cubic cm 1 cubic cm = 1 milliliter 150 cubic cm = 150 milliliter Answer ≈ 450-455 ml
The radius of the base of the cylinder is: 5.64 cm
The question cannot be answered since the base of a cylinder is a circular area whose measurements should be in square units.Furthermore, the question contradicts itself. If the radius is 4 cm then the base cannot be 50 cm^2 and if the base is 50 cm^2 then the radius cannot be 4 cm.Finally, there is no information on the height of the cylinder.
The volume of a cylinder is the area of its base's area times the height (you will prove this in Calculus). Thus the formula you need to use is: pi * radius^2 * height. I will let you do your own homework from there.
A cylinder whose radius is 6cm and height is 20cm has a lateral area of approximately 753.98cm2
The question does not specify what the required formula is for: the volume of an open cylinder, height, radius, surface area, etc. Furthermore, information on the total surface area of a cylinder will not provide sufficient information. A short wide cylinder can have the same surface area as a tall thin one. For example, radius 5 cm and height 4 cm or radius 4 cm and height 7.5 cm or radius 3 cm and height 12 cm or radius 2 cm and height 20.5 cm etc all have the same total surface area. But in each case the value of the other measure, for the open cylinder will be different.
The volume of sand in the cylinder is the area of the circular base multiplied by the height of the layer. The area of the circular base is πr^2, where r is the radius (3 cm), and the height of the layer is 1 cm. So, the volume of sand is π * 3^2 cm^2 * 1 cm = 9π cm^3, which is approximately 28.27 cm^3.
