How calculate radius of dish end size from pressure vessel diameter?

Calculating the radius of dish end size from the pressure vessel diameter is easy. All you have to do is add the blank radius by scaling the drawing from the side and you add five percent.


If the radio of a circle is 14 inches how much is its diameter?

You mean radius. The radius is half the height of a circle. The diameter is the full height. So, you would add 14 to itself.Therefore, the diameter of the circle is 28 inches.


What is the formula to find the perimiter?

It depends what shape you are trying to find. If it is a circle, use the following:C = DpiCircumference = Diameter x PiTake the diameter of the circle, or twice the radius, and multiply it by pi, which is ~3.14If it is any other shape, just add up the sides if they are given.


What is the square ft of a cylinder 18 by 32?

The answer will vary, depending on which of the two is the height, and which is the diameter of the base. To get the surface area, add up the two circles and the mantle, that is, use the formula: area = 2 x pi x radius2 + 2 x pi x radius x height, or the equivalent (2 x pi x radius)(radius + height).


What is the formula in getting the total area of a cylinder?

The surface area of a (circular) cylinder is the circumference of the circle times the height If you need to add the surface of the ends then add twice the area of the end circles. Given r as the radius of the (circular) cylinder and h as the height, the area A is: (2*pi*r*h) + (2*pi*r2)*2 = A

If the diameter is 15 then what is the radius?

Always remember: the radius is half the diameter (or the diameter is 2 times the radius). So divide 15 by 2, and you get 7.5, the radius is 7.5. Don't forget to add the unit ;)

How do you divide a 20 diameter circle into 9 equal segments?

Forget the diameter. Find the centre. Draw any radius. Next, add another radius at 360/9 = 40 degrees to the first. Keep adding radii as you go around the circle. When it is in 9 equal slices you will have returned to the first radius. Done.


Are circles similar or congruent?

Similar, in most instances. All their interior angles add to 360 (without exception), however, the measure of the diameter, perimeter (etc) could be different.


How many angles do circles have?

The angles around circles add up to 360 degrees


What is the surface area when the radius is 4 feet and the height is 6 feet?

assuming you're asking about a cylinder here...for the curved exterior surface, calculcate the circumference (pi x diameter, or 2pi x radius) and then multiply by the height. if the answer also needs to include the ends of the cylinder, then add twice the area of an end or the twice quantity of pi x r squared. circumference x height = rounded surface area of cylinder: 3.14(8') x 6' = 150.72 square feet plus the cylinder ends; twice pi x square of radius = area of cylinder ends: 2[3.14(4' x 4')] = 100.48 square feet so, the total surface area of a 6' high cylinder with a 4' radius = 251.2 square feet.


What is the diameter of a 2.5 inch circle?

add the radius. so you get 5in. i hope it help if need more just ask. i am in 4th grade but i know 8th grade. so you can be safe


Tell swimmingbird to add me please?

Swimmingbird can add you when you tweet him and explain to him why you want him to add you to his circles.
