The answer would be C. What you will do is use the Midpoint formula. (x1+x2/2, y1+y2/2).
Hope this helps! (:
T-2r=x
t=x+2r (In terms of t)
I really hope this helps.
Answer:
8 units
Step-by-step explanation:
Note that 120 degrees represents 1/3 of 360 degrees. The arc described here is thus 1/3 of the circumference of this circle.
Find this circumference and then multiply that result by 1/3:
The formula for the circumference of a circle with radius r is C = 2πr. Here,
(1/3)*(2)(π)(4 units) = 8.38 units, or (to the nearest integer) approx. 8 units.
