A(–2, 4), B(4, 4), C(4, –2), D(–2, –2)
-> select some diagonal: AC
midpoint is at A+(1/2)*AC
-> calculate vector AC:
AC=(4-(-2),-2-4)=(6,-6)
-> calculate half length of AC:
(1/2)*AC=(3,-3)
A+(1/2)*AC=
(-2,4)+(3,-3)=(1,1) which is the midpoint
so the first option is correct

Answer:
Step-by-step explanation:
From the table attached we find,
Number of shaded triangles = 1
Area of each shaded triangle = 256 square inches
Now we can complete the table following the same pattern,
Step number Number of shaded triangles Area of the shaded triangles
0 1 256
1 3 256 × 3 = 768
2 5 256 × 5 = 1280
3 7 256 × 7 = 1792
Answer:
SA = pi cm^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi *r
Pi = 2 * pi *r
Divide each side by 2 pi to find the radius
pi/ 2 pi = 2 pi * r/ 2 pi
1/2 = r
We want to find the surface area
SA = 4 pi r^2
SA = 4 pi (1/2)^2
SA = 4 * pi *1/4
SA = pi
