Acircle with the circumference 12 has an arc with a 48 degree central angle

The radius of this circle is 14.26 units.

Step-by-step explanation:

Next time, please include all of the instructions.

Here:  "A circle with the circumference 12 has an arc with a 48 degree central angle.  Find the radius of the circle."

arc length formula:  s = r·Ф, where Ф is the central angle in radians.

The 48° angle is equivalent to 0.8412 radians (180° ↔ π rad).

Solving s = r·Ф for r, we get:

      s

r =

      Ф

                                  12

which here is r = = 14.26

                             0.8412 rad

The radius of this circle is 14.26 units.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
