Answer: the answer is 3ft because one bit is 2ft + the cirly bit is 3ft
Answer:
x=-4
Step-by-step explanation:
Point a would lie at the same point from the beginning.
EXPLANATION
say point a is x,y. Reflecting over the y axis makes it -x, y. Reflecting over the x axis makes it -x, -y. Finally rotating it 180 degrees would make it x,y, the same spot as in the beginning.
Surface Area is the area of each face added together. For this question lets find the area of one triangle first.
Area of a triangle is base*hight/2, so 6*7/2=21. That was the area of one triangle. We have 4 traingle so we multiply that by for. 21*4=84.
Now, lets find the area of the squre. area of square is side*side or side^2.
So we multiply 6*6=36. that is the area of the square.
To find the surface area, we must add Area of Triangles+Area of Square.
so, 84+36=120
So the surface area is 120
