If by this you mean perpendicular bisectors, then they would intersect at one point.
Answer:
0.8188 or 82%
0.0000643
Step-by-step explanation:
Given that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .0278 in.
If x is the dimension then X is N(0.0276, 0.0001)
Or
is Normal (0,1)
a) Fraction of shelf depths are in specifications
=
b) For 98% to be within the specifications,

Margin of error = 
For 98% critical value Z two tailed is 2.33
Hence std error = 
So sigma should be = 0.0000643
First you will need to split the object into three 2D figures, two circles and a rectangle. Then you will calculate the area of each of these and add them all together.
Circles:
a = <span>πr^2
a = </span><span>π(1.5)^2
a = 7.065
Then find the area of the rectangle.
a = lw where l is length and w is width.
since this is a cylinder, the circumference of the top will be the length.
c = 2</span>πr
c = 2<span>π(1.5)
c = 9.42
a = lw
a = 9.42 x 4.5
a = 42.39
Now add everything up and remember that there are two circles, at the top AND bottom.
7.065(2) + 42.39 = 56.52
The answer is 56.53 inches.</span>
