The ideal radius Alan must control is 
cm.
<h3>Define perimeter of circle.</h3>
The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The area of a circle determines the space it takes up. A circle's diameter is equal to the length of a straight line traced through its center. Usually, it is stated in terms of units like cm or m.
Given data -
Perimeter of circular plate = 10
cm
We know that perimeter of a circle is 2r
Therefore 10 = 2r
r = 5 cm
The given error Alan can make is +-1 cm.
Minimum radius is given by
2r = 10 - 1
r = 
r = 5 -
Maximum radius is given by
2r = 10 + 1
r = 
r = 5 +
The ideal radius Alan must control is cm.

The value of 7 in 870,541 is 10,000
<span>y = tan^−1(x2/4)</span>
tan(y) = x2/4
sec2(y) = x/2
y′ = xcos^2(y)/2

<span>y′ = <span>8x/(<span>x2+16)

You do 9x27=243 then take 2x31=62 add 243+62=305 then take 305 and subtract it from 28 305-28=277
so if i did it right you should get n=277
