B.
Step-by-step explanation:
3:30 to 5:30 is 2 hours elapsed time.
5:30 to 5:45 is 15 minutes elapsed time.
2 hrs + 15 mins =2 hrs 15 mins.

90cm2
We have that the coordinates given are for a sphere.
As we look for a circle parallel to the xy plane, then our xy coordinates are:
(x, y) = (4, 2)
The standard equation of the circle is:
(x - h) ^ 2 + (y - k) ^ 2 = r ^ 2
where h and k are the x and y coordinates of the center of the circle and r is the radius.
We have then:
h = 4
k = 2
r = 3
The equation of the circumference is:
(x - 4) ^ 2 + (y - 2) ^ 2 = 9
answer
(x - 4) ^ 2 + (y - 2) ^ 2 = 9
12. Neither (They are vertical angles)
13. Supplementary (add to 180 degrees)
14. X+68=180 so x=180-68=112 degrees
