Answer:
The diameter is twice that, or approx. 7.90 units.
Step-by-step explanation:
the equation for the volume of a cylinder of radius r and height h is
V = πr²h. Here we need to calculate the diameter after having found the radius. Solving V = πr²h for r², we get:
V
r² = -----------
πh
Substituting the given values, we obtain for r² the following:
145 units³
r² = ------------------------ = 15.6 units²
3.14159(5 units)
Taking the square root of both sides, we get:
r = √15.60, or approx. 3.95 units.
The diameter is twice that, or approx. 7.90 units.
The town will spend $202.5 on laying the pipes.
Step-by-step explanation:
Given points are;
(-2,-4) and (6,-5)

Distance of two points is;

As one unit represent a mile, therefore,
Distance = 8.1 miles
Cost of laying 1 mile = $25
Cost of laying 8.1 miles = 8.1*25 = $202.5
The town will spend $202.5 on laying the pipes.
