Answer:
22.3 km²
Step-by-step explanation:
The formula for the area of a circle is
A = πr²
r = ½d, so
A = π(½d)² = ¼πd²
A = ¼ × π × (16/3)² = ¼ × π × 256/9 ≈ 22.3 km²
Answer:
84
Step-by-step explanation:
I don't really know how to explain it but I'll try my best
Visualize line AB extending past point A (like it does at point B)
You'll see that 180 ( line AB ) minus 129 is 51
Angle 51 is vertical to the other angle inside the triangle that is unnamed.
Now you have 2 angles.
180-45-51=84
Your problem did not have an operator between the x and 1 so I did it as subtraction and addition. There was no answer choice -3 so D x=-9 is the answer
