Answer:

    3631.681108 ft^2

Step-by-step explanation:

The surface area of a cylinder is

SA = 2pi r^2 + 2pi r h  where r is the radius and h is the height

    = 2pi (17)^2  + 2 pi (17)(17)

    = 578pi +578pi

    = 1156pi

Approximate pi with the pi button

    3631.681108 ft^2

The segments shown below could form a triangle.​
Triss [41]

Answer:

False

Step-by-step explanation:

It's been a while since I did this but here we go:

So to find if the triangle lengths are possible, we take the shorter two lengths and we add them.

Those shorter two lengths sum have to be <em>greater</em> than the longest length.

I hope this helps.

What is the vertex of this equation Y-7=-1/16(x-10)^2
VLD [36.1K]
The formula for a vertex form equation is
y = a(x - h) + k
in which (h,k) represents the vertex

Your equation is in vertex form, if you mpve the -7 to the other side you will get
y =  -  \frac{1}{16} (x - 10) ^{2}  + 7
because you have to add 7 to both sides

based on the equation,
h=10
k=7
(h,k)=(10,7)

your vertex is (10,7)
