Answer:
10.7(4.2)+15.9 equals 60.84
51.25+43.85+14 equals 109.1
Answer:
(3, 0)
Step-by-step explanation:
The easiest way to do this problem is to average the x-coordinates and y-coordinates.
So, (0 + 6) / 2 = 6/2 = 3 = x and (2 - 2)/2 = 0/2 = 0 = y
Therefore, the midpoint is (3,0)
let's first off notice that, on the 2), the sector is really half of the whole circle, and on 3) the sector is one quarter of the whole circle.
now, on 2) AB is the diameter of 4 units, therefore it has a radius of 2, or half that.

Answer:
No
Step-by-step explanation:
No, because s is less then 2. 7 is not less then 2.
‘Hope that helps! :)
