<h2>Height of smaller cone is 14.29</h2>
Step-by-step explanation:
For the first cone
Height, h = 18
Radius, r = 12
Substituting
Volume of new cone formed is half of the older cone.
Volume of new cone = 0.5 x 2714.34 = 1357.17
For the cone as the height reduces to 18 radius reduces to zero.
We have
0.467h₁³ = 1357.17
h₁ = 14.29
Height of smaller cone = 14.29
Answer:
Option 3.
Step-by-step explanation:
It is given that a triangle sits on a line and forms 2 exterior angles on the left and right of the triangle of (2h) degrees.
The top interior angle of the triangle is 40 degrees.
From the given figure it is clear that
(Supplementary angle)
(Supplementary angle)
According to the angle sum property of triangle, the sum of all interior angles of a triangle is 180 degree.
Combine like terms.
Divide both sides by -4.
The value of h is 55.
Therefore, the correct option is 3.
