A pyramid is a three dimensional figure with the base in the form of a triangle and three slant sides to it. To find the surface area of a pyramid you have to find the area of the different pieces that make it up. The pyramid base can be triangle or even other geometric figure like pentagon. So first draw the base of the pyramid separately and compute its area first. Now compute the area of each sides separately. The area of each side can be same if the pyramid is a regular pyramid. Some time...
This video tells us the method to find the surface area of an aluminium can or cylinder. The surface area includes the outside area of the curved portion and the aluminium top and bottom. The formula to find area is the multiple of 2, pi, r, r+h or (2)(pi)(r)(r+h). The radius of the cylinder is the radius of the circular top or bottom. In the example shown in the video, the radius is 4 inches and the height is 12 inches. Substituting the values in the formula, we get the surface area as (2)(3...

Brightstorm explains how to use definite integrals to find area. There are two basic area problems: one in which the area lies between the function and the x-axis, and one where the area lies between the two functions. In the first case, if the curve lies above the x-axis for x=a to x=b, the definite integral returns the area. If it lies below the x-axis for x=a to x=b, then the definite integral returns a negative area. In the second case, we assume that f(x) is the higher curve and g(x) is ...
