Answer:
256 cm^2
Step-by-step explanation:
2 of triangulars can be together to become a new square.
because these 2 triangulars have a symmetric shape.
So the all area is 10×16 (the square in the center) + (6×16)
All area is 160 + 96
= 256 cm^2
* the formular of the square area is the width × the length
You can take it apart. There are a top and bottom (both the same) right triangle. So you can find the area of that by multiplying 8*6 and divide by two. Then multiply by two because there are 2 triangles.
You are left with three rectangular sides: One 10x10, one 10x6, and one 10x8.
So your whole equation looks like this: A = 2[(8*6)/2]+(10*10)+(10*6)+(10*8)
64
There are 6 options so it would be 2^6
If you don’t count the empty set it would be 63.
I’m pretty sure this is right I did it in my head so lmk if I’m wrong lol
Answer: B
Step-by-step explanation:
When calculating a circle, you have to find the radius, before you can find circumference, and then finally, when you find the area.
P(x, y) Q(x,y)
P(-2, -1) start at 0. Go to the left two squares, then go down 1 square. mark a point there
Q(2, 4) start at 0. Go to the right two squares, go up 4 squares. mark a point there.
connect two points
make a right triangle
Then use the pythereom
