Answer:
B: 21.99
Step-by-step explanation:
recall that for a circle, circumference is given by:
circumference = 2π x radius
= π x diameter
we are given taht the diameter is 7 cm and π = 3.14
simply substitute these values into the formula for circumference:
circumference
= π x diameter
= 3.14 x 7
= 21.98
(the closest answer to this is B: 21.99)

Answer: Choice D) Vertical Angles</h3>
Reason:
When two lines cross to form an X shape, the opposite pairs of angles are known as vertical angles. They are always congruent to one another.
They do not have to be vertically aligned (meaning the angles could be sitting side by side). Example: In problem 15, angle 1 and angle 3 are vertical angles that are congruent.
