The endpoints of a circle's diameter are (5, -4) and (5, 4). What is the area of the circle in terms of pi?

Step-by-step explanation:

d and r are the diameter and radius, respectively.

d = 8 units

r = 8/2 = 4 units

area = πr² = 16π square units.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
