Answer:
V = 549.5 ft³
Step-by-step explanation:
The formula for the volume, V, of a cylinder of radius r and length h is
V = πr²h.
Substituting 2.5 ft for r and 28 ft for h, we get the volume
V = 3.14(2.5 ft)²(28 ft), or
V = 549.5 ft³
In order for two lines to be perpendicular, their gradients must multiply together to get -1
7*b=-1
7b=-1
Divide both sides by 7
So, the gradient of line b is -1/7
The least miles per gallon this trip is 25 miles per gallon
<h3>How to determine the least miles per gallon?</h3>
The given parameters are:
Distance = 450 miles
Tank size = 18 gallons
The least miles per gallon this trip is calculated as:
Miles per gallon = Distance/Tank size
This gives
Miles per gallon = 450/18
Evaluate the quotient
Miles per gallon =25
Represent as an inequality
x >= 25
Hence, the least miles per gallon this trip is 25 miles per gallon
