Check the picture below.
notice the midpoint of the diameter segment, is just 1,9.
also, recall the radius is half the diameter, notice how long the radius is, just 4 units.
615 miles, because you do 205*3
Answer:
10
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
d = √(-8 - -2)² + (9 - 1)²
d = √(-6)² + (8)²
d = √(36) + (64)
d = √100
d = 10
Given
centre of circle O(3,2)=O(x0,y0)
point on circle P(6,-2)
Standard equation of circle:
(x-x0)^2+(y-y0)^2=r^2
r=radius of circle
= (distance OP)
= sqrt((6-3)^2+(-2-2)^2)
=sqrt(3^2+(-4)^2)
=sqrt(25)
=>
r^2=(sqrt(25))^2=25
Equation of circle
(x-x0)^2+(y-y0)^2=r^2
(x-3)^2+(y-2)^2=25 ............... standard equation of circle
Hey You!
You know 27 is closer to 30 because the number is above 25, and it would take 7 blocks to get closer to 20 and only 3 to 30.
