It would be D because the formula is: pi r^2
Answer:
19.48 m
Step-by-step explanation:
The formula that is used to find arc length is:
arc length = 2πr 
In this question, r = 9m and the angle (θ) = 124°. Substitute the values into the formula.
arc length = 2 × π × 9 ×
= 2 × π × 9 × 0.3444
= 19.48 m
Answer:
idont knowwwwwwwwwwwwwwwwww
Step-by-step explanation:
B + (-2) = 0
Here, we need to do the inverse operation, and apply it to BOTH sides of teh equation.
b -2 = 0
+2 +2
b = 2
Now we have our answer, b = 2
Final answer: b = 2
