The arc length is 6985, the arch height is 950, and the radius is found

The length of the arc l 2 [where a is the long radius and b is the short radius, representing the root number.

According to this approximate formula, it can be found.

In a circle, the segment that connects the center of the circle to any point on the circle is called the radius of the circle. It is usually denoted by the letter r. In a sphere, the segment of the line connecting the center of the sphere to any point on the surface of the sphere is called the radius of the ball.

The radius of the circumscribed circle where the regular polygon is located is called the radius of the circumscribed regular polygon in the circle, and the relevant calculation method is: (1) the circumference of the circle = 2 r (2 * pi * radius) (2) the area of the circle = r (pi * radius) (3) diameter = 2r (the diameter is twice the radius).

The arc length is 8270, the arc height is 990, find what is the radius.

Hello, glad to answer for you! If the arc disturbance length is l, the arc height is h, and the radius is r, then there is the following formula for slow drafting: l = 2 r h rr = lh ) So, under the strip pedan piece you gave, the radius is:

r = 8270*990/π)

In a clustered circle, the line segment that connects the center of the circle to any point on the circle is called the radius of the circle. It is usually denoted by the letter r. In a sphere, the segment of the line connecting the center of the sphere to any point on the surface of the sphere is called the radius of the ball.

The radius of the circumscribed circle where the regular polygon is located is called the radius of the circumscribed regular polygon in the circle, and the relevant calculation method is as follows: (1) Circumference = 2 r (2 * pi * radius) (2) Circle area = r (circumferential wisdom * radius permeability) (3) Diameter = 2r (diameter is twice the radius).

Summary. Radius = (arch height arch height + half chord length chord length half of chord length) (arch height 2) arc length 7600 arch height 2820, find the radius.

You're talking about a chord length of 7600, right??

Yes. I received it, and the radius of this circle is boring. 7600 2=3800(2820 2820+3800 3800) (2 2828)=

Radius = (Arch height Arch height + half the chord length Half the chord length) (Arch height 2) What is the radius? The radius is.

Summary. Hello! We're happy to answer for you!

Hello dear, I know that the chord length and arch height can be calculated like this: radius = (chord length chord length 4 arch height arch height) 2

The arc length is 1450, the arch height is 270, what is the radius?

Hello! We're happy to answer for you!

Hello dear, I know that the chord length and arch height can be calculated like this: radius = (chord length chord length 4 arch height arch height) 2

The answer is: r=(1450 1450 4 270+270) 2=Thank you! You're welcome. I wish you good health and a fulfilling life.

Summary. The arch height sin(l 2r)tan(l 4r) has a known radius of 5050The arc length is 9639 to find the arch height.

The arch height sin(l 2r)tan(l 4r) results are.

Summary. After calculation, if you simply use the arch height and arc length to find, it is very troublesome to solve a system of equations, and the best way is to calculate the chord length according to the arch height and arc length.

Then use the arch height and chord length to calculate the radius, which is very simple.

The arc length and arch height are known as the radius.

Hello dear, it is a pleasure to serve you! I am Mr. Dong Xiaoming, and I am good at mathematics, physics and chemistry. I will provide you with the process and answer the rough case within 5 minutes, please wait for a while.

Dear, please tell me what the arc length and radius are.

What is the arc length and arch height.

After calculation, if you simply use the arch height and arc length to find, it is very troublesome to solve a system of equations, and the best way to take the road is to calculate the chord length first according to the arch height and arc length. Then use the arch height and chord length to calculate the radius of the opening and the opening is very simple.

Dear, do you have any other questions? If you are satisfied with me, please close the order and give me a compliment. If you have any questions in the future, you can ask me questions to do orange qiao, and the specific steps are:

The radius (r) can be calculated from the arch height (h) and arc length (c). The formula is:

r = h + c^2 / 8h)

In this situation, we know that the arch height h = 495 and the arc length c = 2970. So:

r = 495 + 2970^2 / 8 * 495)r = 495 + 2970^2) /3960r = 495 + 887,900) /3960r = 495 +

r = so the radius is.

Solution: Let the arc be l, the corresponding center angle of the arc is , the radius is r, and connect the arch and the center of the circle, then there is l=r* =2050, r-r*cos( 2)=500, two equations with two unknowns, and r is obtained

It's hard to figure it out, so I'll definitely adopt it.

l=r* =2050, r-r*cos( 2)=500, according to this equation, you can use software. I use the test algorithm without software, I use the test algorithm to find r = , at this time the corresponding arc length should be more accurate this test r = 1000,900,950,960,955,954,953 ,,, a total of nine times.
