g Activity 1: The equation y=√(a^2-x^2 ) ,-a≤x≤a, is the upper half of the circle centered at the origin with radius of a. Rotate this curve about the x-axis generate the sphere centered at the origin with radius equals to a. Use the disk method to show that:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

a) is $10.34

b) is 6 toppings

yep b and c r the correct got it! : )
