609 is the answer to this question .
No radius = no circle
The radius defines how big a circle is.
0 radius means the circle is only a dot.
So, the area of the circle is 0.
Or technically, algebraically --
area = πr²
area = π(0)²
area=π(0)
area = 0
Answer:
-20 - (-20) = 0
Step-by-step explanation:
Since the problem starts with a negative number, you need to find out how many units from 0 it is. Since it is 20 units away from 0 in the negative direction, you need to add 20 in the positive direction to make it 0. Subtracting a negative number makes it positive. 2 negatives make a positive, so the problem is stated (rearranged) : 20 - 20 = 0.
Because three negative numbers multiplied give a negative :
(-1) (-1)(-1) = -1
Step-by-step explanation:
take the point as (x,y)
