The ideal radius Alan must control is cm.
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 = 2
r
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.
