Answer:
y = 4 - 2x
y = -2 + 2x
y = -2 + 2x
x = 11
pease tell me if I got them wrong
Answer:
Step-by-step explanation:
28. Area of the circle = π
where r is the radius of the circle.
Given diameter = 14m, therefore radius =
= 7m
Now area of the circle = 49
or = 49 * 3.14 * 3.14 = 483.12![m^{2}](https://tex.z-dn.net/?f=m%5E%7B2%7D)
29. Volume of cylinder = π
h = π*
* 3 = 6.75π cu. feet or 21.195 cu. feet
30. A ball resembles a sphere. Volume of the sphere = ![\frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D)
Given diameter = 30inches; Therefore, radius = 15 inches
Now, Volume of the ball =
= 4500π cu. inches or 14310 cu.inches
