Answer:
The Circumference of the circle is 18.84 ft.
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- Radius (r) = 3 ft
- π = 3.14
<h3><u>To Find</u>;</h3>
- Circumference of the circle = ?
<h3><u>Formula</u>;</h3>
Here,
Diameter = 2 × Radius
d = 2(3) ft
d = 6 ft
Now,
C = πd
C = 3.14 × 6
C = 18.84 ft
Thus, The Circumference of the circle is 18.84 ft.

The mechanical advantage is the ratio of the radii: 5/0.5=10.
Answer:
2
Step-by-step explanation:
The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.
So we are going to need to corresponding y coordinates.
What y corresponds to x=1? y=3
What y corresponds to x=2? y=5
So we have the ordered pairs (1,3) and (2,5).
Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.
(2 , 5)
-(1 , 3)
-----------
1 2
The average rate of change is 2/1 or just 2.
Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.
So just find the factors of 90
90=2 times 3 times 3 times 5
so the factors could be
2,3,15
2,9,5
6,3,5
10,3,3
