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
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 = 
Given diameter = 30inches; Therefore, radius = 15 inches
Now, Volume of the ball =
= 4500π cu. inches or 14310 cu.inches

Answer: 12√2
Step-by-step explanation:
This is a 45-45-90 triangle. In this triangle, a and b are equal lengths, therefore hypotenuse, c, is x√2.
Since a and b is 12, c is 12√2.
10° is your answer for the angle
Answer:
Once again, it’s a nonlinear function.
Graph is not in a straight line.
It has arrows on it’s ends.
Step-by-step explanation:
This line is squiggly. It is bent at the origin and some others. It also has arrows at the line’s ends.
