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
Answer:
Length of BD = +6x - 40
Step-by-step explanation:
In parallelogram ABCD , diagonals AC and BD intersect at E .
In a parallelogram , the two opposite sides are parallel and equal in length.
Also opposite angles of a paralleogram are equal .
Here the length of the parts of a diagonal is given.
BE = - 40
DE = 6x
Since the length of whole diagonal is the sum of the lengths of the parts of the diagonal ,
Length of BD = BE + DE
= -40 + 6x
Length of BD = +6x - 40
