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 total square footage 2,070 Sq Ft
It would be
A) 13 = 9 + 4
B) 7 - 4 = 3
and
E) 20 divided by 4 = 5
Since all of these values would match on each side of their respective equations after solving
Explanation: 54 yards is about 162 feet, and since we are converting measurements we need this ( duh ) and 135 seconds is approximately 2.25 minutes, so what we need to do is is divide the numbers like any conversion problem: 162 divided by 2.25 is 72.
Hope this answer helps!
Answer: 9
Step-by-step explanation:
12 insulators = 183/4 hours
x = 281/8
x × 183/4 = 12 ×281/ 8
183x/4 = 6 × 281/4
183x / 4 = 1686 / 4
4 cancel out 4
183x = 1686
Divide bothside by 183
x = 1686/183
x= 9.21311
x = 9 approximately.
