Plz asapthe circumference of a redwood tree trunk is 16π ft, and it is 100 ft tall. what is the approximate volume of the redwood tree trunk?
2,560π ft3
640π ft3
25,600π ft3
6,400π ft3

The approximate volume of the redwood tree trunk is

Step-by-step explanation:

we know that

The volume of the cylinder (approximate volume of the redwood tree trunk) is equal to

where

B is the area of the base

H is the height of the tree

step 1

Find the radius of the base

The circumference is equal to

we have

substitute and solve for r

Solve for r

step 2

Find the area of the base B

The area of the base of cylinder (tree) is equal to

we have

substitute

step 3

Find the volume

we have

substitute

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
