Answer:
33.6
Step-by-step explanation:
this is a circle
so
the area of a circle = pi x radius squared(since it's a 2-D shape)
but this is 3-D
so
V = 2664.31 = (4/3)(
)
you could also use
A = ³√(36 * π * V²) when A is the surface area
but those are too long, so let us just use the answer choices
V = 3.14 x answer choice x radius sqaured
V = 3.14 x 8.6 x radius sqaured
2664.31 = 3.14 x 8.6 x radius sqaured
radius sqaured = 2664.31/3.14 x 8.6
radius sqaured = 2664.31/27.004
radius sqaured can't be made with this
lets skip V
radius sqaured = 2664.31/3.14 x 17.2
radius sqaured = 2664.31/54.008
since 27.004 didn't work, and 54.008 is 2 times as that
radius sqaured = 2664.31/3,14 x 33.6
radius sqaured = 2664.31/105.504 ≈ 25
25 square rooted is 5
so
33.6
So you have 9x-10 and x= -5
9(-5)-10
-45-10= -55
Your answer would be -55
Answer:
x=20 and y=16
Step-by-step explanation:
4x - 6y= -16
since y=x -4, we substitute it in place of "y"
Then, 4x - 6(x-4) = -16
4x - 6x + 24 = -16
-2x+24= -16
-2x= -16-24
-2x= -40
Divide both sides by -2 then,
x=20
once we get the value of "x" we substitute in place of "y=x-4"
y=20-4
y=16
