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.

You would need too do 5*5=25 if you did 5*7=35 that would be wrong
No she not correct. 80% of the students are wearing tennis shoes
Answer C. 317.8 would be your answer:) Hope this helps!
Answer:
The correct option is C: the isotope of iodine contains 81 neutrons.
Step-by-step explanation:
The mass (A) of the iodine isotope is given by:
Where:
Z: is the number of protons
N: is the number of neutrons
For iodine Z= 53, so if A = 134 the number of neutrons is:
Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.
I hope it helps you!
