Step-by-step explanation:
Percent error=6-5.5/5.5*100
Answer:
18. x= 15
19. x = 32.5
20. 82.097
Step-by-step explanation:
because any trianglw with 65 degrees the other abgle will be equal making the side equal as well
180-115= you know
Answer:
x1= -5
x2= 2
Step-by-step explanation:
Answer: The correct option is (D) pie.
Step-by-step explanation: We are to select the correct number that produces an irrational number when multiplied by pie.
We know that if one of number is a non-zero rational number, then for the product to be irrational, we must have the other number irrational.
Give number is 2/5, which is rational. So the other number must be irrational.
Out of the given options, first three numbers are rational.
Only the last number pie is irrational. Because, the digits after the decimal are non-repeating and non-terminating.
So, the product will be irrational, if the other number is pie.
Thus, the correct option is (D).
Answer :)
- Approximate Circumference = 43.96
- Exact Circumference = 43.982297
Step-by-step explanation:
Formula <u>U</u>sed: C=2πr
Step 1:
Divide Diameter by 2.
14ft / 2ft = 7ft
Radius = 7ft
<u><em>Explanation:</em></u>
The radius is the length from one inner side of a circle to the middle. While the diameter or a circle is the entire length across!
Step 2:
Multiply 7 (radius) times 3.14 (approximate pi) times 2
7 x 3.14 x 2 = 43.96
Approximate Circumference = 43.96
<u><em>Explanation: </em></u>
The question states that you are to find the approximate circumference <u>AND</u> the exact circumference. The difference is pi. You may have seen the pi symbol on your calculator when calculating exact circumference. It looks like this π. But sometimes we are asked to find the "not exact circumference" that is called the 'approximate' circumference. The not so scientific pi is shortened to 3.14.
Step 3:
Multiply 7 times π times 2
7 x π x 2 = 43.982297
Exact Circumference = 43.982297
I hope this helps!
