It is clear that (AB) is a median, and it is obvious that the angle is 90, thus it is an altitude and a perpendicular bisector
The last one isn’t
there can’t be more than 1 of the same x value
I attached an image with the complete question.
Answer:volume of attic = 1526.04 ft³
Explanation:Volume of cone can be calculated using the following rule:
Volume =

* area of base * height
Volume =

* π * radius² * height
We are given that:
π = 3.14
radius = 18/2 = 9 ft
height = 18 ft
Substitute in the equation to get the volume as follows:
Volume =

* 3.14 * (9)^2 * (18) = 1526.04 ft³
Hope this helps :)

D. Undefined
Step-by-step explanation:
It is a vertical line so it has no slope.
Answer:
8.06
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 7^2 = c^2
16 + 49 = c^2
65= c^2
Find the square root of 65
