-- On a flat, 2-dimensional (x-y) graph, the locus of all points that are
4mm from a given line consists of two more lines, one on each side
of the given line, and all three lines are parallel.
-- If we want to talk about 3-dimensional space, then the locus of all
points that are 4mm from a given line is a cylinder, with radius of 8mm,
and the given line is the axis of the cylinder.
Answer:
21.46
Step-by-step explanation:
Find the area of the square:
10cm×10cm= 100cm
find the are of the circle:
![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D)
r=5
![\pi (5)^{2}](https://tex.z-dn.net/?f=%5Cpi%20%285%29%5E%7B2%7D)
area of the circle=78.5398163397
Find the difference
100-78.5398163397=21.4601836603
21.46 is the shaded area
(4x+1)(x^2-3)=0
x= -1/4 or +sqrt 3, -sqrt 3
