Answer:
6
Step-by-step explanation:
A = pi r^2
C = 2 pi r
A = B (area)
3C = B
sub C = 2 pi r into 3C = B, and A = pi r ^ 2 into B
3 (2 pi r) = pi r ^ 2
6 pi r = pi r^2
( divide both sides by pi )
6r = r^2
r^2 - 6r = 0
r(r-6) = 0
r = 0 or r-6 = 0
radius can not be 0 , therefore r = 6
hope this makes sense, might be little confusing sorry!
24-3x=-27
Subtract 24 from both sides
-3x=-3
Divide by -3 on both sides
X=1
Answer:
The area is 15 feet
Step-by-step explanation:
So you are going to need two different equations-
l = w(3)
2l + 2w = 40
Insert the first equation into the second-
2(3w) + 2w = 40
Simplify this equation-
6w + 2w = 40
8w = 40
Divide both sides by 5
w = 5
Solve first equation
l = 5(3)
l = 15
Then find the area-
5 x 15 = 75
Answer:
Step-by-step explanation:
We want to write the conjugate of the complex number:
Recall that the conjugate of a complex number in the form <em>a</em> + <em>b</em>i is <em>a</em> - <em>b</em>i, and vice versa.
We can rewrite our complex number as:
Hence, <em>a</em> = 0 and <em>b</em> = 6.
Then its conjugate will be:
