What is the formula for finding the area of a cylinder?
To find the surface area of a cylinder add the surface area of each end plus the surface area of the side.
Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end.
There are two ends so their combinded surface area is 2 π * r2.
What is the area and volume of a cylinder?
The formula for the volume of a rectangular solid, V=Bh V = B h , can also be used to find the volume of a cylinder. For the rectangular solid, the area of the base, B , is the area of the rectangular base, length × width. For a cylinder, the area of the base, B , is the area of its circular base, πr2 π r 2 .

What is the formula for the area?
The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width.
What is the formula of total surface area of a cylinder?
The general formula for the total surface area of a cylinder is T. S. A. =2πrh+2πr2 .
What is the area of the sphere?
Therefore, the Surface Area of a Sphere with radius r equals 4πr2 .
What is the formula for volume?
The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times. This results in the formula: Volume = side * side * side.

What is the area?
In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.
What are the formulas for triangles?
|A triangle with one right angle. C = A + B = Pi/2 radians = 90o c2 = a2 + b2 (Pythagorean Theorem)|
|P = a + b + c s = (a+b+c)/2 K = ab/2 ha = b hb = a hc = ab/c ma = sqrt(4b2+a2)/2 mb = sqrt(4a2+b2)/2 mc = c/2|

What is the area of quadrilateral?
To find the area of a rectangle, you need two measurements: the width, or base (the longer side of the rectangle), and the length, or height (the shorter side of the rectangle). Then, just multiply them together to get the area. In other words: Area = base × height, or A = b × h for short.
