What happems to the height of the sun in summer and winter?
it is 'bigger' in summer. although the arc remains roughly the same, you are just seeing the tip of the arc in winter, and more of the same arc in summer. in very northern or southern places, winter can mean not seeing any arc of the sun whatsoever (totally dark for days or months) or seeing part of the arc constantly (meaning the sun is always up in summer or always down in winter, such as antarctica and parts of far north Canada and Greenland)
What are arcseconds and how are they used?
A second of arc (arcsecond, arcsec) is 1⁄60 of an arc minute, 1⁄3,600 of a degree.When it comes to astronomy, you will find the term "arc second" used in three ways: (1) to express a given distance in declination on a star chart, (2) as a given unit of an astronomical object's size, and (3) as an expression of a telescope's resolving power.
What is the first step in constructing an angle congruent to a given angle?
The first step in constructing an angle congruent to a given angle is to place the compass point on the vertex of the given angle. Then, draw an arc that intersects both rays of the angle. This arc will help transfer the angle's measure to the new location where you will construct the congruent angle.
What does the name Joan of Arc mean?
Joan of Arc is a heroin because she had stood up for everything she believed in. in doing so she as able to change the world. Joan's morals and preachings have given equal rights to all. she helped unite all of France and defeat England.
Is there a special day named after Joan of Arc?
Joan of Arc Day (the feast of Joan of Arc) is on May 30.
How do you determine the radius of a circle when you only know the arc?
Given an arc or segment with known width and height, the formula for the radius of a circle is:r = (H÷2) + (W2÷8H)Where: W is the length of the chord defining the base of the arc and H is the height measured at the midpoint of the arc's base
How do you find radius of a circle if given arc length?
you will need to know the angle subtended by the arc; arc length = radius x angle in radians
How do you find the central angle of a circle if I am given the arc length and radius?
(arc length / (radius * 2 * pi)) * 360 = angle
What is the radius of curvature?
The radius of curvature of a circle, or an arc of a circle is the same as the radius of the circle.For a curve (other than a circle) the radius of curvature at a given point is obtained by finding a circular arc that best fits the curve around that point. The radius of that arc is the radius of curvature for the curve at that point.The radius of curvature for a straight line is infinite.
Given a circle with a radius of 8mm and an arc with a length of 4.2 mm what is the degree of the arc?
The degree of the arc is: 30.08 degrees.
What is the radius of a circle with a sector are of 662.89?
Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
What is an arc central angle and radius of the circle?
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
What does a cone net look like?
A circle with a radius equal to the base of the cone. This circle will be tangential to a segment of a circle whose arc is the same length as the circle, and whose radius is the slant height of the cone.
How does radius affect arc length?
The arc length of a circle is directly proportional to its radius. Specifically, the formula for arc length (L) is given by (L = r \theta), where (r) is the radius and (\theta) is the central angle in radians. This means that as the radius increases, the arc length also increases for a given angle. Conversely, for a fixed radius, a larger angle will result in a longer arc length.
How do you work out the area of a sector when given the length of the arc?
If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)
Given a circle with a radius of 6 what is the length of an arc measuring 60 degrees?
The length of an arc measuring 60 degrees given a circle with a radius of 6 is 2*pi, that is 6,2831 approximately.The perimeter of a circle is calculated with the formula:L = 2 * pi * rwhere L is the perimeter and r the radius of the circle. This is equivalent to calculating the length of an arc measuring 360 degrees. The length of any arc smaller than 360 is proportionally smaller. Given that 60 degrees is 1/6 of the total circle (360), the length of the arc will be 1/6 of the perimeter.2 * pi * 6L = --------------- = 2 * pi6
If An ARC measures 120 degrees what is the length of the radius of the circle?
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
