A cone has a volume of 488 cubic inches and a diameter of 12 inches. The volume of a cone can be found by using the formula V = 1 third pie R squared H, where r is the radius of the base of the cone and h is the height of the cone. What is the approximate height of the cone?6.5 inches9.6 inches12.9 inches25.8 inches

12.9 inches

Step-by-step explanation:

V=1/3²

3V=² h

h=3V/r²

h=3(488)/(6)²

h=1464/36

h=12.9446...

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
