Answer: Each piece should be 7 inches long.
All circles are similar shapes.
However, we can prove that these circles are similar by finding their radius-circumference ratios.
<h2>Circle B</h2>
Radius:
Circumference:
Radius/circumference ratio:
<h2>Circle D</h2>
Radius:
Circumference:
Radius/circumference ratio:
The radius/circumference ratio for both the circles is , thus making the two circles similar.
Answer:
Quadratic
Step-by-step explanation:
This is because quadratic equations require a variable squared. Most numbers have two square roots, a positive and a negative. So, the implementation of (variable)² in an equation will most likely have x ± (variable) as an answer.

Step-by-step explanation:
Probability helps us to know the chances of an event occurring. The correct option is A.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
Dependent events are those events in which the outcome of the first event affects the outcome of the second event. The statement that is correct about the dependent event is that the probability of all dependent events can be calculated using the "OR" formula P(A+B) =P(A) +P(B)-P(A and B).
Hence, the correct option is A.
