Answer: 4 units
Step-by-step explanation:
Given : AB is the diameter of a circle.
Then, the central angle for arcADB must be because the central angle subtended by diameter is .
The length of arc is given by :-
Hence, the length of the radius of the circle = 4 units

Since you already have the circumference, you will divide 56 (Circumference) by pi. Which will get you the diameter*
Formula :: C/
Answer:
Step-by-step explanation:
Given the expression in the form , we know that Victoria can simplify it by adding the like terms:
She can also factor out -6:
Now, she needs to factor the coefficient of the second term rewrite it as (1-2), then:
Now she needs to group the terms as following:
And factor out 2x:
Finally, she has to factor out . Therefore, she gets:
