If the figure rotated clockwise then it would be -90, if the figure rotated counterclockwise then it would be 90, and if the figure appears to not have moved at all it would be 0.
Hope this helps! ;)
Answer:
See below.
Step-by-step explanation:
Formula: A = πr²
Since the radius is 4, we fill in the formula with the radius.
A = (3.14)4²
A = (3.14)16
A = 50.24

Answer:
C
Step-by-step explanation:
Complementary angles add up to 90°, so you can use the equation, 90°= 67°+X°. To solve this, you need to subtract 67° from both sides to get 23°=X°
Let S = his average speed.
Let D = distance traveled one way
Time = distance / speed
Set up an equation:
d/6 + d/12 = 2d/S
Multiply the equation by 12s:
12s(d/6) + 12s(d/12) = 12s(2d/s)
Simplify to get:
2sd + sd = 24d
Combine like terms:
3sd = 24d
Divide both sides by d:
3s = 24
Divide both sides by 3:
s = 24/3
s = 8
His average speed was 8 mph.
