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 i get surface area of a circular spa with a 12 foot diameter?

To calculate the surface area of a circular spa, you can use the formula for the area of a circle: ( A = \pi r^2 ), where ( r ) is the radius. For a spa with a 12-foot diameter, the radius would be 6 feet (half of the diameter). Plugging this into the formula gives you ( A = \pi (6)^2 \approx 113.1 ) square feet. Therefore, the surface area of the spa is approximately 113.1 square feet.


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).

How do we use diameter in the real world?

The diameter of a circle is used in various real-world applications, such as calculating the area and circumference of a circle, determining the size of circular objects like wheels, pipes, or plates, and in engineering and construction for designing structures with circular components. It is also essential in fields like astronomy for measuring the size of planets and stars.


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.


What is diameter indent?

A diameter indent is a measurement feature on a part or component that specifies the desired diameter that a circular feature, such as a hole or boss, should have. This dimension helps ensure proper fit and alignment of mating parts during assembly. Manufacturers use diameter indents to accurately control the size and tolerance of circular features in mechanical components.


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.
