Great question! I had this question in Geometry on Edmentum.
Answer: Height of cone = 3y
Step-by-step explanation:
We know that the cylinder and the cone have the same volume. The cylinder has radius x and height y. We will make use of the formulas:
Volume of cylinder = πr²h
Volume of cone = 1/3πr²h
Since the cone has radius 1/3x, we will have to make its height 3 times of y (the height of the cylinder) to make both the cylinder and the cone have the same volume.
So, the height of the cone is equal to 3y.
Hope this helps, and have a wonderful day! :D

Answer:
See below.
Step-by-step explanation:
Let the side have a length x units .
The triangle formed by an altitude is a 30-69-90 triangle so the sides are in the ratio 2:1:√3 where √3 is the altitude. Therefore if the side of the triangle = x then altitude = √3 * x / 2 = √3x/2.
So we need to prove that 3x^2 = 4 (√3x/2)^2.
Simplifying:-
4 (√3x/2)^2 = 4 *( 3x^2/ 4) = 3x^2. This completes the proof,
your question is how many minutes per hour can she be on her phone. 1 hour equals 60 minutes. so the answer would be 60 minutes per hour.
