This is a problem of Difference-of-squares. We know that for a difference of squares

the factorization is given by:

To learn this you need to remember that a <em>difference</em> means <em>subtraction.</em> So applying those concepts we can solve this problem step by step.
Applying distributive property:

Applying distributive property again:

Simplifying:
<em>The correct answer is C</em>
Answer:
the one for the finding the height is 3.3, the one with 7 as the height is 351.86, and the one with 3 as the height is 150.8
Step-by-step explanation:
h=V
πr2=41.5
π·22≈3.30247
V=πr2h=π·42·7≈351.85838
V=πr2h=π·42·3≈150.79645
You will need to find the volume! so you would multiply 12x7x3 and you should get 252yards! Make sure to show your work and i hoped this helped! :D

Answer: 349.99 Newton must be exerted on the small piston
Step-by-step explanation:
In changing a tire a hydraulic jack lift 7468 newtons on its large piston which has an area of 28.27 cm squared. Pressure is expressed as force/area
Pressure exerted and transmitted to the smaller piston is
7468/28.27 = 264.14N/cm²
If the small piston has an area of 1.325 cm squared, the force that would be exerted on the smaller piston is
Force = pressure × area
= 264.14 × 1.325 = 349.99 Newton
