Circumference = 2 pi r

2 pi r = 200

r = 100 / pi

Area of base = pi r r

Area of base = 100*100 / pi

Area of base = 3183.1 sq. m.

PLEASE HELP ASAP THIS IS THE LAST QUESTION AND I AM STUCK!!
Varvara68 [4.7K]
<h3>Answer:  B) 7 units</h3>

===========================================================

Explanation:

The y coordinates of the two points are the same, so we can subtract the x coordinates and apply absolute value

|R - T| = |-6 - 1| = |-7| = 7

Or we can say

|T - R| = |1 - (-6)| = |1 + 6| = |7| = 7

Either way, the two points are 7 units apart.

You could use the distance formula to get the same answer, but that's definitely overkill in my opinion. The trick mentioned above also could work if the x coordinates were the same, but the y coordinates were different. In any other case, you would have to use the distance formula.
