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:
Step-by-step explanation:
We assume the given sum is the sum of interior angles of a triangle, so is equal to 180°.
48° +X +(X -44°) = 180°
2X +4° = 180° . . . . . . . . . . collect terms
X +2° = 90° . . . . . . . . . . . .divide by 2
X = 88° . . . . . . . . . . . . . . . subtract 2°
Then the other interior angle is ...
(X -44°) = 88° -44° = 44°
The unknown interior angles are ...
1 over 5a to the 2nd power
I hope this helps the answer is
