Answer:
<h2>
C = 113.04 m</h2><h2>
</h2>
Step-by-step explanation:
circumference of a circle = 2πr
where
radius (r) = 18m
π = 3.14
plugin values into the formula
C = 2 (3.14) 18
C = 113.04 m
-4y = 8x
Divide both sides by -4
y = -2x
This is in the form of y = kx, where k is the constant of variation.
y = kx is the direct
That means, k = -2.
The constant of variation is B. -2.
Answer:
D 81 pi units^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
18 pi = 2 * pi *r
Divide each side by 2 * pi
18 pi / (2 pi) = 2 pi * r/ (2 pi)
9 = r
Now we can find the area. Area is given by
A = pi r^2
A = pi * 9^2
A = 81 pi units^2
it is true; just work them out, you should get what they got :))
