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

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
