The surface area of a cylinder can be found by breaking it down into three parts: The two circles that make up the ends of the cylinder. The side of the cylinder, which when "unrolled" is a rectangle Combining these parts we get the formula: Area = 2 x pi x r x h + 2 x pi x r2 π is Pi, approximately 3.142 r is the radius of the cylinder h height of the cylinder

The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area is surfaces of a shape, it included the base, length and the height

Math Term Definition. Volume. Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, cylinder or pyramid. It's units are always "cubic", that is, the number of little element cubes that fit inside the figure.

To draw a net of a cylinder you need to to draw a rectangle and then draw two circle which are the same size on the long side of the rectangle. You have to make sure the length of the rectangle is the same length as the circumference of the circle

A cylinder is a geometric solid that is very common in everyday life, such as a soup can. If you take it apart you find it has two ends, called bases, The bases are always congruent and parallel to each other. If you were to 'unroll' the cylinder you would find the side is actually a rectangle when flattened out.

Diameter: A diameter is a chord that runs through the centre point of the circle. It is the longest possible chord of any circle. The centre of a circle is the midpoint of its diameter. That is, it divides it into two equal parts, each of which is a radius of the circle. Radius: From Latin: radius "staff, spoke of a wheel" 1. A line from the centre of a circle to a point on the circle. 2. The distance from the centre of a circle to a point on the circle. Pi: Pi is a ratio of the circumference of a circle's to it’s diameter. In another word, pi equals the circumference divided by the diameter. Circumference is equal to pi times the diameter. No matter how large or small a circles is, pi will always work out to be the same number. Pi is an irrational number, which means that is a real number with nonrepeating decimals expansion. It cannot be represented by an integers ratio and foes forever. Otherwise known as infinite decimals. There’s no exact value, seeing as the number does not end. Height:. Height is a measure of a polygon or solid figure, taken as a perpendicular from the base of the figure.

The circumference of a circles is the distance around the outside of the circle orthe perimeter of the circle. Circumference has a relationship to pi, because pi is is defined to be the ratio of a circle circumference.
