First, determine the circumference (C) of the circle, the equation,
C = 2πr
Substituting the value or the radius,
C = 2π ( 4) = 8π
The arc length is the product of the circumference and the ratio between the subtended angle and 360. The mathematical expression is already,
S = (8π) x (72 / 360) = 0.8π
Thus, the arc is 0.80π.
Answer:the answer is (0, 4).
Step-by-step explanation:
The <u>equation</u>
consists of five <u>terms</u>, three of them contain <u>fractions.</u> The <u>denominators</u> of these fractions are 2, 4 and 6.
Find the LCM(2,4,6). Since
then LCM(2,4,6)=2·2·3=12.
Thus, you have to multiply each term of the equation by 12 to eliminate the fractions.
Answer: 12

Answer:
Circle graphs
A circle is the same as 360°. You can divide a circle into smaller portions. A part of a circle is called an arc and an arc is named according to its angle.
A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.
