That's a good question. I have never thought about that. But yes, for anything excluding circular objects, length and width are used.

What is the square footage of a pool 8 feet in diameter by 2 feet deep?
Assuming a circular pool, divide the diameter by 2 to get the radius, then use the formula for the area of a circle. The depth is not relevant for this problem.
What is the surafce area of circular clarifier fifty five diameter?
Divide the diameter by two to get the radius. Then you can use the standard formula for the area of a circle, which I copy here for your convenience: area = pi x radius squared
Why you have to calculate hydraulic diameter to find Reynolds number?
The Reynolds number is the relationship between inertial forces (numerator) and viscious forces (demoninator). The terms in the numerator are usually the fluid density, velocity, and "characteristic" dimension (which has units of length). Depending on the type of problem you are trying to solve that characteristic dimension may be a length (flat plate problem) or a diameter (flow in a round tube), or hydraulic diameter (non-circular internal flow). Since a non-circular cross section has more surface area than a circular cross section area there needs to be a way to account for this difference. If you use the hydraulic diameter equation to calculate the hy. dia. of a circular cross section, you will get the diameter of the circle.
How do you find perimeter of cylinder?
You just need to find the circumference of the circular base (or top). It's the same thing. (Hint: use C=pi*diameter to find the circumference).
One can use two-dimensional objects to build three-dimensional objects.?
Only if you have two dimensional objects of specific sizes in specific combinations.
How do you use a circular loom?
The same way you use a linear loom, only in a circular fashion.
Why you use pi in circular shape's formula?
Because the circumference of a circle divided by its diameter is equal to pi.
Why we use pi in circular shape's formula?
Because the circumference of any circle divided by its diameter is equal to the value of pi which is an irrational number.

What are the advantages of knowing the diameter of the field of view at a given magnification?
You can use that to estimate the size of objects that you are observing.
How much will it cost to fence a circular swimming pool at the edge of the pool if it has a diameter of 35 feet and fencing costs 12.50 per foot (use 3.14)?
The answer is 1373.75

What are function of vernier caliper?
we use it for measuring absolute value of any objects like hallow tubes and diameter of copper wires etc,.
Who use a caliper?
Calipers are used to measure objects. They are used by machinists who make objects from metal that must meet size standards. They are also used by carpenters to measure things like the diameter of a rod.
If the height of a circular cylinder is 5 and the diameter of the base is 4. what is the distance from the center of one base to a point on the circumference of the other base?
The square root of 29 You can use pythagoras.
