Answer: Endpoint = (-4,6)
Step-by-step explanation:
To find any endpoint use the formula

multiply each by 2 to simplify
take the equations and simplify
6+
= 2 -2+
= 4 =
-6 -6 +2 +2
= -4
= 6
To check use the Midpoint formula

√8
for the equations of circles: x²+y²= (radius)²
The area of the cross-section is 169 sq. cm.
