What angle measure, in radians, corresponds to a central angle of 180° in a circle with a radius of 2 units?

Select one:

a. pi /2

b. pi./4

c. pi

d. 2pi

180 degrees is the same as pi radians.

Step-by-step explanation:

In order to convert angles from degrees to radians we must, apply the following formula:

rad = degree*pi/180

Since degree in this case is 180, we have:

rad = 180*pi/180 = pi

So the answer is "c". We must notice that the radius of the circle won't change the central angle, it doesn't matter how big or small the circle actually is, we can simply apply the formula for the conversion.

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.
