It is D, not here because they are all dependent.
The area of your circle is about 530.93 m
The diameter of your circle is 26 m, just multiply your radius by 2
The circumference of the circle is about 81.68
The equation to finding the area is
pi x r x 2
3.14 times 13 times 2
The equation to finding the diameter
r x 2
radius times 2
The equation for finding circumference
pi x d
3.14 times 26
Let me know if im wrong, otherwise I want brainliest, PLEASE!!
Answer:

Step-by-step explanation:

That bracket symbol, with an r in it, means "the absolute value of r".
So r's absolute value is -2 meaning r is two units from zero
r= 2
The value of the number is 80,000
