The radius of the cylinder should be approximately 2.040 inches long.
<h3>How to calculate the radius of a rocket to contain a required quantity of powder</h3>
The volume required to store the powder is the sum of the volumes of the cylinder and the cone, whose expression is in this case:
204 in³ = (π/3) · r² · (4 in) + π · r² · h
204 in³ = (4/3 + h) · π · r²
204 in³ = (4/3 + 7 · r) · π · r²
204 = (4π/3) · r² + 7π · r³
7π · r³ + (4π/3) · r² - 204 = 0
The <em>positive</em> roots of the <em>cubic</em> equation are:
r ≈ 2.040 in
The radius of the cylinder should be approximately 2.040 inches long.

The probability that one person chosen has blue eyes is 0.57.
The given parameters:
- <em>Number of females, = 60 </em>
- <em>Number of males, = 70</em>
- <em>Probability of choosing a female with blue eyes, = 0.41</em>
- <em>Probability of choosing a male with blue eyes, = 0.7</em>
The total number of female and male with blue eyes is calculated as;
Total female with blue eyes = 0.41 x 60 = 24.6
Total male with blue eyes = 0.7 x 70 = 49
Total blue eyes = 24.6 + 49 = 73.6
The probability that one person chosen has blue eyes is calculated as follows;
Thus, the probability that one person chosen has blue eyes is 0.57.
