Question
What is the height of the shape formed by the sectors shown below? A circle is cut into 8 equal sections. The sections are arranged into the shape of a parallelogram with a base of pi r and height of question mark.
a. r
b. d
c. pi times r
d Pi times d
Answer:
a. r
Step-by-step explanation:
In the diagram shown, we can see the sections are divided into 8 and each has a radius of r
The 8 sections from the circle is used to form the a parallelogram.
If we take a look at the diagram of the parallelogram closely, we can see definitely that it still showing the divided 8 equal sections using to form it.
Hence, the height of the parallelogram = the radius of the circle.
Therefore, height of the shape formed by the sectors is r
Step-by-step explanation:
please repeat the question again and I'll solve in the comments the question isn't too clear
The apothem is the distance from which the altitudes of the triangle to one of its sides. It can be calculated through the equation below,
tan 30° = apothem / 0.5(length of side)
Substituting the known values,
tan 30° = 5 / 0.5x
The value of x from the equation above is 17.32. Multiplying this value by 3 (because a triangle has 3 sides), we get an answer of 51.96 cm or approximately equal to 52. Thus, the answer is letter B.
First you have to define what a rational and irrational number is and they would be:
a / b, where b can never be 0.
Irrational are the numbers with non-periodic decimals, how the roots are not exact, the number pi, etc.
The student says "the difference of any irrational number and any rational number is rational"
The student's mistake is to use "any" since not any rational number would be the case that fulfills this.
That is, the correct thing is that there is an irrational number and a rational number in such a way that their difference is rational.
