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.

Answer:
157.44 feet
Step-by-step explanation:
Given that:
Lance is out for sightseeing in Rome.
Lance went to see the Colosseum.
Height of the outer wall of the Colosseum = 48 meters
Unit Conversion formula:
1 meter = 3.28 feet
To find:
Height of the outer wall of the Colosseum in feet.
Solution:
It is simple problem for the conversion of unit where we already know the value in one unit and the conversion formula as well.
We have to simply find how much 48 meters will be when converted in feet.
1 meter = 3.28 feet
48 meter = 48 
3.28 = <em>157.44 feet</em>
Answer:
Step-by-step explanation:
Let x represent the number of bananas that Tommy eats.
Let y represent the total number of pieces of fruit that the monkey eats.
Every day, his monkey eats 4 apples in the morning. The monkey also eats two bananas for every banana that tommy eats. This means that the number of bananas that the monkey eats is 2x. The expression for the total number of fruits eaten by the monkey becomes
y = 2x + 4
