Answer:
18.84 feet
Step-by-step explanation:
The circumference of a circle can be found using:
c=π*d
The radius is given, but we have to find diameter. The diameter is twice the radius, or
d=2r
The radius is 3 feet. Substitute 3 in for r.
d=2*3
d=6
The diameter is 6 feet.
Now we have the diameter. We can substitute 6 in for d in the circumference formula. We can also substitute 3.14 in for pi.
c=π*d
c=3.14*6
c=18.84
The circumference is <u>18.84 feet</u>
Y=4
How?
When they say directly you should multiply the x and y together. You would get -24, now using that number divide -24 by the new x(-6) you would get 4.
Hellooooo!! Marie Here!!!
The answer is here:
The value of "x" is 9
<h3>Hope This Helps!!! Have A GREAAATTTT Day!!</h3>
-2x - 4y = 1
<u>12y</u> = <u>-6x - 3</u>
12 12
y = -0.5x - 0.25
-2x - 4(-0.5x - 0.25) = 1
-2x + 2x + 1 = 1
0x + 1 = 1
<u> - 1 - 1</u>
<u>0x</u> = <u>0</u>
0 0
x = 0
-2(0) - 4y = 1
0 - 4y = 1
<u>-4y</u> = <u>1</u>
-4 -4
y = -0.25
(x, y) = (0,-0.25)
