There are 5280 feet in a mile
There are 3600 seconds in an hour
to get 40 miles per hour
we multiply 40 by 5280 and divide by 3600
40 * 5280 / 3600
this gets us 58.666666...
but since they want us to round to the nearest whole number, our answer would be 59 feet per second
Answer:
V = a (x + 4)*5 but see below.
Step-by-step explanation:
You're not going to get any kind of answer that gives V = 122 or some other pure number.
Formula
V = arh
Givens
a = pi * r
r = (x + 4)
h = 5cm
Solution
V = a * (x + 4)*5
or
V = pi * (x + 4)^2 * 5
There is no indication of which one to choose.
The fixed amount is 6 because it's 6 dollars for 0 miles traveled.
