In a unit circle, what is the length of an arc that subtends an angle of <br> π/4 radians?
olchik [2.2K]

A unit circle has radius 1, and thus circumference 2\pi.

Since an angle of \frac{\pi}{4} is one eighth of a whole turn, the length of an arc that subtends an angle of  \frac{\pi}{4} radians will be one eighth of the whole circumference:

l = \dfrac{2\pi}{8} = \frac{\pi}{4}

In fact, the radians have the property that, in the unit circle, the length of the arc is exactly the measure of the angle. In general, you have

l = r\cdot\alpha

where l is the length of the arc, r is the radius and \alpha is the angle in radians. So, if r=1, you have l=\alpha

A rectangular rug has the perimeter of 36 feet. The length of the rug is twice the width. What is the length
777dan777 [17]

Answer:

12 ft

Step-by-step explanation:

l = 2w

P = 2(l+w)

36 = 2(2w+w)

36 = 2(3w)

36 = 6w

Divide each side by 6

36/6 = 6w/6

6 =w

l = 2w

l = 2(6)

l = 12
