Explanation Given: The function is f ( x ) = 1 2 x + 4 bounded by y = 0 , x = 0 , x = 5 . Approach: If f ( x ) is nonnegative and R is the region between f ( x ) and the x -axis from x = a to x = b , the volume of the solid formed by rotating R about the x -axis is given by, V = ∫ a b π [ f ( x ) ] 2 d x Calculation: The graph of the function f ( x ) = 1 2 x + 4 bounded by the curves is shown in Figure ( 1 ) . Figure ( 1 ) Volume of the solid of revolution is calculated as, V = ∫ a b π [ f ( x ) ] 2 d x ... ( 1 ) Here, x = a and x = b are x -intercepts . Substitute 0 for a , 5 for b and 1 2 x + 4 for f ( x ) in equation ( 1 ) .

Optimization

Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the se…

Integration

Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integratio…

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects th…

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
