Step One
Develop a formula for the perimeter.
Argument
What you see is a semicircle going upwards and another one going downwards. Two semicircles =1 circle.
The "perimeter" [Circumfrence] of a whole circle = 2*pi*r
We are told that whatever you call this the perimeter is 8pi + 16
Step Two
Set up the equation
8pi + 16 = 2*pi*r + 4r Including the line connecting these two.
Step Three
Take out the common factors on the left and right.
8(pi + 2) = 2r(pi + 2) Divide both sides by pi + 2
8 = 2r Divide by 2
4 = r
Sorry. I didn't know the meaning of perimeter. Mathmate is perfectly correct.
Step-by-step explanation:
Linear pairs = 180°!!!!!
- 1st angle is 2[x]-39 2nd angle is just x
- soooo add the x. 3x-39=180
- 3x=141 x=47
X is just the second angle!!!!!
lol. i toonk geo last year and i cant believe i still remember all this hopefully i got it right!
What can you be more specific like a put it in a sentence. For example x*-260+7=?
Answer: The probability for both is 1/2
Step-by-step explanation:
For A. The probability for who do or do not participate in some kind of sport is found by adding the students who do or do not. Which is 25 + 225 = 250
250 out of 500 simplified is 1/2
For B. The probability got who do and do not participate in some kind of sport is found by taking the number of students out of the whole number. Its 250 out of 500.
250 out of 500 is simplified to 1/2.
