Find the measure of the central angle of an arc if its length is 43.98π and the radius is 18.

7.68 radians

Step-by-step explanation:

The arc length formula is s = rФ, where Ф is the central angle.

                                                                  s

Solving this formula for Ф, we get Ф =

                                                                   r

                                                                                      43.98π

and in this particular case, the central angle is Ф = , or

                                                                                         18

approximately 7.68 radians.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
