To compute the area of the circle, we first observe that since the diameter of the circle is 8 inches, its radius is 4 inches. Now we use the formula for the area of a circle: A = πr2

For example, we can instead calculate the area enclosed by a circle of radius r using vertical slices, in which case the transverse coordinate is horizontal: t = x, and so δt = δx.

PART 3 MODULE 9 PROBLEMS INVOLVING VOLUME Again we will be examining a variety of “real-world” problems that can be solved by referring to familiar facts from elementary geometry. These …

In section 6.1 we return to the relationship between area and the integral and learn to apply that relationship to nd the exact area of more and more more complex regions.

Here dA is the area of the smaller blocks and q the pressure per unit area. The only principle to be followed in dividing a bigger area into smaller blocks is that the width of the smaller block should be …

Find the length of the intercepted arc in cm. (Ans: 3 5π ) 2) Find the area of a sector in square cm of a circle of a radius 6 cm if the central angle is 60ο.

10 Program #2: The Faces Write a program that reads a le containing the vertex coordinates of a tetrahedron and which then computes: the area of each faces; the three angles formed by the face; …
