Answer: The result of the division is the number pi.
And the approximation of pi is: pi = 3.14
Step-by-step explanation:
The distance around a circle is called the perimeter of the circle.
The distance across a circle (This is a line that starts on one point of the circle, go through the center of the circle, and end in the next time it intersects the circle) is called the diameter of the circle.
The quotient between these two quantities is maybe one of the most famous numbers in the world, is the number pi, written as:
π = 3.14159265358979...
Is an irrational number, which means that the decimals keep going infinitely.
Then we can conclude that:
"The result of dividing the perimeter by the diameter, is equal to the number pi = π = 3.14159265358979..."
Because this is an irrational number and is actually impossible to write it, we usually use pi = 3.14 to aproximate it.
Answer:
380
Step-by-step explanation:
The surface of a square pyramid is made up of a single square in the center, and four triangles on the sides. The square's area is 10*10=100, while the area of each of the triangles is 10*14/2=70. Multiplying this by the 4 triangles, you get 280. Adding them together, you get a total of 380 square meters. Hope this helps!
The answer: 660
Explanation:
First you need to fine 1/5 of the students, which is 165, since 4/5 of them voted you multiply 165 by 4. Giving you the answer of 660 students voted.
Hope this helps :)
brainliest? Lol
