Volume of a cone V = pi * r * r * h / 3
so V = 45, r = 2 therefore 45 = 3.14 * 2 * 2 * h /3 => 45 = 3.14 * 4 * h /3
=> 135 = 3.14 * 4 * h => 33.75 = 3.14 * h => 10.75 = h
height = 10.75 cm rounded to 2 decimal places
Answer:
<h3>45 different permutations</h3>
Step-by-step explanation:
Given 10 letters with 8 identical H's and two identical T's, the number of different permutations will be expressed as;


<em>Hence the number of different 10-letter permutations that can be formed from 8 identical H's and two identical T's is 45</em>
The answer is sqrt17 or 4.123
