## How do you calculate the length of a curve?

If the angle of your arc is measured in degrees then use this formula to calculate the length of the arc:

1. Arc length (A) = (Θ ÷ 360) x (2 x π x r)
2. A = (Θ ÷ 360) x (D x π)
3. A = Arc length.
4. Θ = Arc angle (in degrees)
5. r = radius of circle.
6. D = Diameter of circle.

Is the length of the long leg of a right triangle?

The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. In this triangle, you know the hypotenuse (the side opposite the right angle) has a length of 10.

### What is the length of a pencil measured in?

In units of measurement of length we use centimeter (cm) to measure. We can use this unit for measuring the length of a pencil, the width of a book etc. but this unit is too big to measure the thicken of a pencil. So we use another unit called millimeter (mm).
