Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
A semicircle is given with radius of 3cm .
And we need to find the perimeter of the semicircle . We know the perimeter as ,
Perimeter = πr
Perimeter = 3cm × π
Perimeter = 3π cm .
Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,
Perimeter = 3π + 6 cm
We were supposed to give answers in terms of π .
<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>
Answer: k ≤ -4 or k ≥ 
<u>Explanation:</u>
| 3k + 4 | ≥ 8
3k + 4 ≥ 8 or 3k + 4 ≤ -8
<u> -4</u> <u> -4 </u> <u> -4</u> <u>-4 </u>
3k ≥ 4 or 3k ≤ -12
<u>÷3 </u> <u>÷3 </u> <u> ÷3 </u> <u>÷3 </u>
k ≥ or k ≤ -4

First you need to find the y-intercept, which is y = -1
Next is we need to find the slope of the line > you are going to have to do this by finding to clear point
The ones that I will be using are: (3, 1); (6, 3) (You could take any points)
Now using the slope formula we could find m.
m = y2-y1 / x2-x1
(1 - 3) / (3 - 6) = m
-2 / -3 = m
m = 2/3
Using the linear function format: y = mx + b
Therefore the equation of the line is y = 2x/3 -1
Answer:
Step-by-step explanation:
x²+y²=r²
r²=12
r=√12=2√3
