# how do you find the radius of an arc

What is the arc length that has a radius of 2, and an angle of 1 radian?The arc width is 1500mm.

The length of the arc and the angle subtended by the arc (not shown in figure) are also calculated.The formula for finding arc length is:Answer substitute the values for radius and angle into the relationship between arc length, radius and angle at the top of the page:

The length of an arc formed by 60° of a circle of radius r is 8.37 cm.This calculator utilizes these equations:

The area of a circle is the space it occupies, measured in square units.So, the radius of the circle is 7 cm.A) the radius of the arc, to the nearest cm.

Try this drag one of the orange dots to change the height or width of the arc.Worksheet to calculate arc length and area of sector (radians).

Arc length = θ × (π/180) × r, where θ is in degree, where, l = length of an arc θ = central angle of arc r = radius of the circle arc length formula in radiansThe arc length is the fractional amount of the circumference of the circle.

Given the area, a a, of a circle, its radius is the square root of the area divided by pi:The blue segment is the arc whose radius we are finding.If you have the diameter, you can also use πd π d where d = diameter d = d i a m e t e r.

Eliminating r gives l = 200 θ sin θ 2, so we can see that θ must satisfy θ = 10 sin 2 θ 2.Auto cad, has a length measurement facility.

R = √a π r = a π.
