Answer:
132cm²
Step-by-step explanation:
Split into two shape: Cube & Triangle prism
Cube surface area:
1) area of top & bottom
(4×3)×2= 12×2= 24cm²
2) area of the sides (only three sides as for surface)
(3×6)×3= 18×3= 54cm²
Triangle prism surface area:
1) area of two sides of triangle:
(½×6×4)×2= (3×4)×2= 12×2= 24cm²
2) area of two sides of rectangle:
(5×3)×2= 15×2= 30cm2
Total surface area: 24+54+24+30= 132cm²

Answer:
–16 – 22i
Step-by-step explanation:
The radius of the circle = 4 + 26i - (-6 + 2i)
= 10 + 24i.
The radius will be the absolute values of this |10 + 24i|.
If a point is on the circle then it's distance from the centre must be 10+ 24i.
-19 + 15i - (-6 + 2i) = -13 - 13i , so this is not on the circle.
-16 - 22i - (-6 + 2i) = -10 - 24i = |10 + 24i| , so this is on the circle.
5 + 16i - (-6 + 2i) = 11 + 14i , so this is not on the circle.
20 - 24i - (-6 + 2i) = 26 - 26i. so this is not on the circle.
