Answer:
V≈615.75
Step-by-step explanation:
V= 3.14r^2 h/3 = 3.14 X 7^2 X 12/3 ≈ 615.75216
For this case we have that by definition, the perimeter of a circle is given by:

Where:
r: It is the radius of the circle.
According to the figure, it is observed that the radius of the circle is 2. Then:

Let's remember that we have a quarter circle:

We round and we have that the correct option is 
Answer:
Option A
The attached figure is the image that completes the question
Step-by-step explanation:
I guess, the question is, how many miles were driven ?
if that is the case, then
we need to deduct the basic fee of $14.75, as this would have been paid, even if they did not drive a single mile.
so, 50.45 - 14.75 = $35.70
that is the actual cost for the driven miles.
how many miles ?
well, how often do $0.15 fit into $35.70 ?
35.7 / 0.15 = 238 miles.
this customer had been driving the moving van for 238 miles.
Step-by-step explanation:
STEP 1
Calculate the slope from 2 points.
STEP 2
Substitute either point into the equation. You can use either (3,7) or (5,11)
STEP 3
Solve for b, which is the y-intercept of the line.
STEP 4
Substitute b, -1, into the equation from step 2.
Multiply 2x-2y=10 by 2,
4x-4y=20,
given:4x-5y=17
y=3
pluck it in
2x-6=10
move the 6 to the right
2x=16
divide
x=8
y=3
