Why is the answer B? Plz explain.
Ivanshal [37]

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.

Helppppp!! I will mark brainliest!!
Yuliya22 [10]

Answer:

If the slopes are different, there is one solution.

If the slopes the same but the y intercepts different, there is no solution.

If the slopes and y intercepts are the same, there are infinitely many solutions.

2x + y = 4

2y = 6 - 2x

Solve for y on both

y = 4 - 2x

y = 3 - x

They are both different, so there is one solution

median means the middle value of any set of data so first arrange the data into ascending order.

16, 25, 30, 49

the data is even so we take both the middle value , add it and divide it with 2
