C= 2*pi*r
pi= approx. 3.14
So
The first one with the radius being 18 would be approximately 113.04
BECAUSE 18 * 2 = 36
36*3.14= 113.04
DO THE SAME PROCESS with the other values you were given...
Also if they give you the diameter the formula is C= d*pi
that formula is the same as c=2*pi*r ..... Use either... just remember when they give you the radius.... the radius is half of the diameter... so take the radius times 2 and times that by pi
When it asked for an approximation use 3.14 for pi.
I'm sure you can do the rest by yourself. I hope this helped!

Answer:
Step-by-step explanation:
The formula for finding the midpoint of two coordinates is expressed as;
M(X,Y) = 
Given the coordinates c(-4,5) and d(-1,-4), x1 = -4, y1 = 5, x2 = -1 and y2 = -4.
For the X coordinate of the midpoint
X = x1+x2/2
X = -4+(-1)/2
X = -4-1/2
X = -5/2
X = -2.5
Similarly for Y:
Y = y1+y2/2
Y = 5+(-4)/2
Y = 5-4/2
Y = 1/2
Y = 0.5
Hence the midpoint coordinate of C(-4,5) and D (-1,-4) is (-2.5, 0.5)
Answer:
Correct answer: (a - 4) · (a + 6)
Step-by-step explanation:
Given:
a² - 4a - 24 + 6a = a² - 4a + 6a - 24 = a (a - 4) + 6 (a - 4) = (a - 4) · (a + 6)
God is with you!!!
