Step-by-step explanation:
We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice cream cone in cubic centimeters.
We will use volume of cone formula to solve our given problem.
, where,
r = Radius
h = Height.
We know that diameter is two times the radius, so radius of cone would be half the diameter that is cm.
Upon rounding to nearest tenth, we will get:
Therefore, the volume of the cone would be approximately 128.3 cubic cm.
The inscribed angle theorem says that
Triangle AOC is isosceles because both AO and CO are radii of the circle and have the same length. This means angles CAO and ACO have the same measure and are congruent.
Angles ACO and COD are congruent because they form an alternating interior pair between the parallel lines AC and OD.
Taking all these facts together, we have
and since angle COB is made up of angles COD and DOB, these angles must be congruent, and so the arcs they subtend (CD and DB, respectively) must also congruent.
