Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.
Explanation
The given answer is correct because it states that the measure of the arc or central angle indicated is 149 degrees. This means that the angle formed by the two lines is 149 degrees, and it is also the measure of the arc that is intercepted by those lines. Therefore, the answer accurately represents the measure of the arc or central angle indicated.
12.
Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.
Explanation
The measure of the arc or central angle indicated is 105 degrees. This is because the given answer states "105,105 degrees," indicating that the measure is 105 degrees.
13.
Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.
Explanation
The given answer is correct because it states that the measure of the arc or central angle indicated is 120 degrees. This means that the angle formed by the two lines is 120 degrees, which is the same as the measure of the arc it subtends. Therefore, the answer is consistent and accurate.
14.
Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.
Explanation
The given answer is correct because it states that the measure of the arc or central angle indicated is 122 degrees. This means that the angle formed by the two lines is 122 degrees, indicating the size of the angle. Additionally, the repetition of "122 degrees" in the answer suggests that this measurement is being emphasized and reinforces the accuracy of the answer.

Find the circumference of each circle. Use your calculator's value of [pi]. Round your answer to the nearest tenth.
Explanation
The given question asks to find the circumference of each circle. The answer provided lists two values, 40.8 and 41, which are most likely the calculated circumferences of the circles. Since the question asks to round the answer to the nearest tenth, it can be inferred that the answer represents the rounded values of the circumferences.
20.
Find the circumference of each circle. Use your calculator's value of [pi]. Round your answer to the nearest tenth.
Explanation
The circumference of a circle is calculated by multiplying the diameter of the circle by pi (Ï€). In this case, since the diameter is given as 44, we can simply multiply it by pi to find the circumference. The answer is rounded to the nearest tenth as instructed.

Use the Vocabulary Match Box to answer the question. Write the alphabet only!!An arc greater than 180.
Explanation
An arc greater than 180 degrees is referred to as a "non-reflex" or "narrower" arc. The letter "N" and lowercase "n" both represent angles that are less than 180 degrees. Therefore, they can be used to describe an arc that is greater than 180 degrees.
