Hello :
note :
<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
</span></span>in this exercice : a =0 b = 0 r =8
<span>the equation of the circle is : x²+y² = 64</span>
What do you need help with?
Usually, the more often it's compounded, the better. That's assuming that the percent is equal through all comparisons, however.
You have to find the difference in height between both checkpoints. To do this just calculate 196 - 52. Checkpoint 5 is 144 (meters?) higher than Checkpoint 2.
