What is that supposed to mean, it is not a question?
Answer:
hundreth, because it is the second digit after the decimal point.
Answer:
- <em>Tangent segments from a common external point are</em> <u>congruent</u>
Explanation:
A <em>tangent</em> line to a circle is a line that touches the circle in only one point of the cirfumference, and, hence, the tangent is perpendicular to (forms a right angle with) the radius of the circle.
There are many thorems relative fo the tangent lines of a cirle.
One of those theorems states that if two tangent lines to a circle are drawn from a same external point, the two segments formed from the coomon external point to the tangency points have the same length.
Also, you must know that, from the definition, two segments of the same length are known as congruent segments.
Therefore, calling P the common external point, A one point of tangency in the circle, and B the other point of tangency, then:
- length segment PA = length segment PB.
- So, the two <u><em>tangent segments from an common enternal point are congruent.</em></u>
Answer:
1. 52.63% 2. 47.36%
Step-by-step explanation:
20 + 18 = 38 total people
20 divided by 38 = 0.5263 to 52.63%
18 divided by 38 = 0.4736 to 47.36%
Hope this helps!
Answer:
26π, 130π, 780π (inches)
Step-by-step explanation:
We first need to find how long the circumference of the circle is, since that is the part of a wheel that determines how far it will go. The formula to find the circumference is 2πr, where r is the radius. This formula is just something you have to remember, there is no way around it.
Now, applying the formula, we find that the diameter of the circle is 26π inches, which means that the bike will go 26π inches every rotation of the wheel.
To find the distance for 5 rotations, we multiply 26π by 5, getting 130π
Similarly, with 30 rotations, we get 26π*30=780π
