Answer:
88 centimeters is the diameter of the cilinder
Step-by-step explanation:
The pressure on both ends of the lift must be the same. Assuming the piston is cilindrical, its area will be A=π*r² where r is half the diameter
Since pressure P=F/A And P1=P2
F1=2000kg.g
A1=π*r²
F2=25kg.g
A2=π*0.05²
2000/(π*r²)=25/(π*0.05²)
and we solve for A1
r²=2000*0.05²/25
r=20*0.05/5=0.44m or 44cm
This is the radius, meaning that the diameter will be twice this number
Answer: 176
Step-by-step explanation:
To evaluate the equation we have to remove the parentheses and add 15 + 17...
1/2 (11)(15 + 17) =
= 11 * 32 * 1/2
Now, we have to turn it into a fraction and multiply it...
=
352 ÷ 2 = 176
I hope this helps!
