Answer:
7.) 53.38
8.) 18.84
9.) 87.92
Step-by-step explanation:
7.)
For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.
The formula for finding the circumference is 2 × π × 8.5
2 × 3.14(π) = 6.28.
6.28 × 8.5 = 53.38
8.)
For the second question, we can see that the radius is now given to us which is 3ft.
The formula for finding the circumference is 2 × π × 3
2 × 3.14(π) = 6.28.
6.28 × 3 = 18.84
9.)
For the third question the raduis is also given to us, which is 14 in.
The formula for finding the circumference is 2 × π × 14.
2 × 3.14(π) = 6.28.
6.28 × 14 = 87.92

Answer:
The equation of the line that goes through points (1,1) and (3,7) is 
Step-by-step explanation:
Determine the equation of the line that goes through points (1,1) and (3,7)
We can write the equation of line in slope-intercept form
where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula: 
We have 
Putting values and finding slope

We get Slope = 3
Finding y-intercept
y-intercept can be found using point (1,1) and slope m = 3

We get y-intercept b = -2
So, equation of line having slope m=3 and y-intercept b = -2 is:

The equation of the line that goes through points (1,1) and (3,7) is 
The answer is A. 102.
