615.4 km³

Step-by-step explanation:

Volume of cylinder

Volume of cylinder = πr²h

Volume of cylinder = πr²h= 3.14 × (7 km)² × 4 km [approximately]

= 3.14 × 49 km² × 4 km [approximately]

= 615.44 km³ [approximately]

= 615.4 km³ [approximately, reducing to the nearest tenths]

V = π · r² · h

V = 22/7 · 7² · 4

V = 22 · 7 · 4

V = 154 · 4

V = 616 km³ → Option A

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
