it is C. i think because this i looked it up trust me
We know that
original volume of a cylinder=pi*r²*h
volume=1692.46 in³
1692.46=pi*r²*h
<span>if the radius becomes three times as large
so
r=3*r
new volume=pi*(3*r)</span>²*h----> 9*pi*r²*h
new volume=9*original volume
new volume=9*1692.46----> 15232.14 in³
the answer is
the new volume is 15232.14 in³
Answer:
11 17/21
Step-by-step explanation:
3,600 widgets in 4 hours
therefore 3,600 / 4 for one hour = 900 widgets
900 widgets in one hour
<h3>Answer:</h3>
- x = 5/6 in ≈ 0.83 in
- v = 125/108 in³ ≈ 1.16 in³
<h3>Explanation:</h3>
The width of the cardboard (in inches) will be 4x, and its length will be (5-4x) so the perimeter adds up to 10 in. Then the volume is the product of the area of the open ends (x²) and the length (5-4x).
The graphing calculator shows that volume is maximized when the value of x is 0.833, or 5/6 inch. The corresponding length is 5-4x = 5/3 inch, so the volume is ...
... v = (5/6)²×(5/3) = 125/108 . . . . in³
The corresponding decimal values of x and volume are ...
... x ≈ 0.83 in
... v ≈ 1.16 in³
