Answer:
Cost, C = $28410.72
Step-by-step explanation:
We have, a concrete pillar has the shape of a cylinder.
Diameter of pillar is 8 m and ts height is 9 m
If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,

The cost of pillar at the rate of $87 per cubic meter will be :

The next set is the parametric equations of the same line .
x = t, y = 5 and z = -t .
What is the meaning of parametric and non parametric?
- The assumptions behind parametric statistics relate to the population's distribution from which the sample was drawn.
- Since no presumptions are made while using nonparametric statistics, data can be gathered from samples that do not fit any particular distribution.
x + y + z = 5, x + z = 0
the line satisfies
x + z = 0 , y = 5
thus
x = t, y = 5 and z = -t .
the first one is technically already the symmetric equations of the line.
thus:
x = -z ; y = 5
the next set is the parametric equations of the same line .
x = t, y = 5 and z = -t .

Answer:
-1/12
Step-by-step explanation:
i took the test
If the time taken by 14 inches wide is one hour then the blade of 12 inches wide will take 1 hour 17 minutes to mow a lawn.
What is width?
The width of something is the measurement of one side of a body. It is generally less than length of that body or shape.
How to calculate time?
We have been given time of 1 hour if blade is 14 inches wide and we have to calculate time taken by 12 inches wide blade:
It will be as 14/12* 1 hour
=14/12
=1.167
=1.17 hour
Hence the time taken by the blade of 12 inches wide will be 1 hour and 17 minutes.
Answer:
Here is the answer, I took it as simple I could.
