Answer:
1. R = 10 in C = 62.8 in
2. R = 13 ft C = 81.64 ft
3. D = 32 yards C = 100.48 yards
4. D = 24 cm C = 75.36 cm
5. D = 16 mm C = 50.24 mm
6. R = 7 in C = 43.96 in
7. R = 9 ft C = 56.52 ft
8. R = 20 yards C = 125.6 yards
9. D = 6 cm C = 18.84 cm
Step-by-step explanation:
Radius = R Diameter = D Circumference = C pi = 3.14
R = D / 2
D = R x 2
C = 2 x pi x R or D x pi
I basically plugged in all the values into the formulas I gave above. If you need more help feel free to ask.
Hope it helps! (:

Step-by-step explanation:
Answer:
m = -4/3 b = 0
Step-by-step explanation:
Slope formula is 

The slope is -4/3. The line intersects the y-axis at (0 , 0) so b = 0. This can be verified by plugging one of the points into the equation.
Let f(x) = y.
y = 4x - 12
Let x = 0
y = 4(0) - 12
y = - 12
This leads to the point (0, -12).
Let y = 0.
0 = 4x - 12
1 2 = 4x
12/4 = x
3 = x
This leads to the point (3, 0).
We now graph both points and then connect each point with a straight line.
Answer:
Step-by-step explanation:
20x - 44z = 84
528x + 44z = 1012
548x = 1096
x= 2
48(2) + 4z = 92
96 + 4z = 92
4z = -4
z = -1
(2, -1)
