So since 11/pi doesn't means 11 divided by pi but it means 11 pi
circumference=2pir
if circumerence=11pi
2pir=11pi
solve for r (radius)
divide both sides by pi
2r=11
divide by 2
r=5.5
area=pir^2
area=pi5.5^2
area=pi30.25
answer is area=30.25pi in^2
Answer:
x = 3
Step-by-step explanation:
The formula for the axis of symmetry is x = -b/(2a).
Here, a = -2 and b = 12, so the axis of symmetry is
-12
x = --------- = 3 => x = 3
2(-2)

Answer:
45.8
Step-by-step explanation:
We need to find the surface area for this entire figure!
We can see that this is a pyramid here - we must find the area of the 3 triangles and the base triangle at the bottom.
The 3 triangles building up the pyramid are all equal to each other.
To find the area of a triangle, use 

Round to the nearest tenth: 45.75 -> 45.8
