The volume of a cone varies jointly with the base (area) and the height. The volume is 12.5 ft when the base (area) is 15 ft? and
the height is 2] ft. Find the volume of the cone (after finding the
variation constant) when the base (area) is 12 ft2 and the height is
6 ft.

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
